Much Less Than Half a Chance Part 4


Screening for the Risk of Deanimation

The term “screening” is used in medicine to describe routine examinations or diagnostic procedures of a defined group of individuals to identify diseases or risk factors for same at an early stage. Screening is usually categorized as a  “preventive medical examination” or a  “checkup,” and its aim is to increase the life expectancy of those examined  by reducing the incidence or severity of life threatening disease and enhancing the quality of life. The most accurate examination methods possible should be used to identify as many diseases as possible still in their non-symptomatic phase, so that early treatment or change in life style can be initiated.

It is critically important to understand that the purpose of a “deanimation screening scan” (DSS) is not primarily to interfere with the course of disease or to extend the duration of life during this life cycle. Rather, it is to predict or to warn of impending  deanimation with increased accuracy and precision. Any contemporary medical or health benefits are thus incidental. Indeed, it is precisely when DSSing is used to determine or influence current medical interventions that it becomes dangerous. Knowing when you are likely to deanimate with greater precision, for sole purpose of improving your cryopreservation, carries little if any risk of iatrogenesis beyond that which would be present if you found out you were dying at a later time, or didn’t find out and suddenly collapsed in cardiac arrest from a heart attack, or suffered a massive stroke. It is only when the course of treatment is altered by obtaining the data, or looking at it (see “The Black Box of the Baseline,” below) that DSSing becomes either a practical or an ethical conundrum.

The first problem we confront in a screening test for deanimation risk is that we are moving in completely uncharted waters. We have no benchmarks or baselines on which to structure our screening program, save for a modest number of pilot programs that have been undertaken to evaluate full body scanning as a primary tool for the detection of cancer and atherosclerosis in the general population, or in selected subpopulations. For now, these will have to serve as the basis for our protocols, as well as the important cautionary lessons learned from other screening programs.

For reasons of safety, (see Radiation & Risk, below) Magnetic Resonance Imaging (MRI) is preferred over Computerized Tomography (CT), because no ionizing radiation is employed in making the image. MRI has some important limitations at this time, most notably only a few centers have devices that image the coronary vessels with sufficient precision  to allow risk  assessment for coronary artery disease (CAD).  Similarly, screening for Alzheimer’s Disease (AD),(beta amyloid deposits) also requires CT-PET scanning and the associated exposure to ionizing radiation.  So, for the present, CT is the only way to screen for CAD and AD. For this reason, and for those who for economic reasons may need to use CT imaging, it is worthwhile to briefly discuss the much hyped “risks” of radiation from whole body CT scans and this is done in some detail below.

Figure 25: Typical finding in an elderly woman who under prophylactic full body MRI scanning during a clinical trial in Germany to determine if full body scanning would reduce morbidity and mortality from cardiovascular disease and cancer. (Gohde, et al.)

A specimen imaging protocol is presented as Appendix 1 and is taken from the study by Gohde, et al., “Prevention without radiation – a strategy for comprehensive early detection using magnetic resonance imaging,” which was itself a pilot study in the use of MRI as a screening tool for cancer and cardiovascular disease.

The Mechanics

Currently, there is only one way to get a  DSS and that is to do it yourself.  There are several reasons, which will be discussed directly, why that is not a good idea, or certainly not the ideal way  to pursue DSSing. There are a number of reasons for this, starting with the potential for harm. Primum non nocere is the first dictum in medicine: first do no harm. Information is the most powerful force in the universe and information concerning you own health and welfare is especially important. It is also information that you cannot be objective about. It just isn’t possible. It is for this reason that no good physician treats himself or his immediate family in life or death matters as the sole or usually even the primary caregiver. In fact, speaking from experience as a person knowledgeable in medicine, I have found that wise counsel and advice I can (and do) easily give to others  is strangely absent from my own ears when I am the patient.

This lack of objectivity is more than a nuisance, it can be truly dangerous; and here I will have recourse to an actual example. The first four people to undergo DSSing have done so over the past 11 months. These were all individuals who were over 60 and who had not had consistent (or recent) “physicals.” All were counseled about the dangers of VOMIT and about the negative psychological impact of potentially finding out “something was wrong.” All four individuals had significant anomalies on their scans – two of which were life threatening and these were (or are) being medically managed.

In the other two cases, the scans revealed anomalies that might merit further medical evaluation in testing, and in both cases, the decision was wisely made not to pursue those tests. Why? That’s a complicated question, and I’ll answer it by explaining the circumstances of one of these people:

Mr. Ling is an 82 year old man who is in excellent health. He is physically active, mentally sharp and still working part time in his profession of many years.  He underwent a DSS five months ago. The findings were, overall, very good. His coronary calcium score was roughly a third lower than expected for his age, he had no signs of neoplasms, or of peripheral or central atherosclerosis, and the only abnormal cardiovascular finding was evidence of mitral valve regurgitation, which was deemed not serious and not likely to progress rapidly. However, a number of nodules were found in his right lung, along with some enlarged lymph nodes. The radiologist who reviewed the scan suggested a possible biopsy, with or without “bronchoalveolar lavage” (BAL).

While Mr. Ling is in good health, he is an 82 year old man and BAL requires sedation with propofol or a similar drug, and carries with it the risk of significant complications.  As to a CT-guided needle biopsy of the lung masses or the lymph nodes, this is this discussion that took place between Mr. Ling and the radiologist who interpreted his scan: “OK, let’s consider what this could be? I’m not sick – never felt better, so it’s not TB or something infectious? And if it’s cancer, well, what kind of treatment options would I have at my age for lung cancer with lymph node involvement?”

Those were great questions, and as it turned out, the radiologist was only playing it safe – he doesn’t want to get sued if Mr. Ling finds out he has cancer and a lawyer says to  a jury, “The doctor who imaged him said, ‘You’re in you 80s, I see this kind of thing all the time. Don’t worry about it.”  The radiologist ended by noting, “Since you are planning on following up in a year with another scan, we’ll see if anything has changed then.” And Mr. Ling is fortunate to have sufficient financial means that if he wants to pop in for a scan two months later, he can do that, too.

The problem is, most people aren’t in Mr. Ling’s position, and many will be unable to reason their way past the information that they have “masses” or “lumps” in their lungs and “enlarged lymph nodes in their chests!” That kind of worry cannot only be expensive, it can be damaging to one’s health, and corrosive to one’s quality of life. The information from DSSing should be given in the proper context, in the proper way, by the proper people, with the proper knowledge.  Absent that, it can do real harm. And if the scan does reveal a grave or untreatable medical condition, then there is all the more reason for the person to have the necessary resources at hand to help him cope and plan.

Ideally, this program would be part of a comprehensive Member Survival Program (MSP) administered by the cryonics organization (CO) and there would be a staff person whose job it would be to maintain communications with members, encourage compliance with MSP protocols (including the preferred imaging protocol) and collect and manage the resulting data stream.

Under such a scheme, upon intake (approval of cryopreservation arrangements) all members would have (at their option) completed a comprehensive health history and demographic information questionnaire, most of which would be completed as part of their membership application. The data from this questionnaire, as well as any electronic medical records the member may choose to provide, would be entered into the CO’s comprehensive member data base. The availability of this data would then allow for downstream refinement of the “one size fits all” scan protocol being proposed here, by allowing for individual risk assessment for CVD and cancer. This would flag members at elevated risk of early onset of these diseases to consider commencing scanning surveillance at an earlier age.

The Schrödinger Scan: the Black Box of The Baseline

Unless otherwise indicated, the first (baseline) scan would be done at age 45 for men and age 50 for women. In order to completely avoid any deleterious negative psychological effects, as well any potentially harmful effects from VOMIT (as discussed above), the baseline scan remains blinded and unexamined for 1 year after it is made. This done by providing written instructions to the radiologist reviewing the scan to seal the report unless there are unequivocal findings of life threatening pathology.

At the end of the year long blind period, the scan is examined and any anomalies noted. If the member chooses, a repeat scan can be done to resolve any questions or concerns raised by the baseline imaging. For example, if what appears to be a suspicious mass or nodule was found, a rescan a year later will very likely disclose if it is a neoplasm e.g., it will have grown or spread). It may seem counter intuitive to not look at data which you have paid for, experienced inconvenience to get, and which “might” save your life, but that is the necessary price that must be paid for this intervention to be used safely.

The baseline scan must be regarded as the first part of something that will not “happen,” or be completed for another year – like a bulb that has been planted to bloom in the spring, or a bond that will not mature for another 12  months. The scan itself is only a part of the process: the necessary information to safely interpret it does not appear until the required interval of time has elapsed. After all, before this protocol was proposed, no one ever got scanned and they felt just fine about it (until they dropped over in cardiac arrest).  For those of a quantum bent, consider it an extended version of Schrödinger’s famous experiment, except instead of the cat in the box, it’s a CAT scan in the box.

Scan Intervals & Exceptions

If the baseline is “negative,” showing no evidence of evolving pathological processes that merit intervention or further monitoring, then it is being proposed that the next scan take place 5 years later. Similarly, with each subsequent negative “healthy” scan, the next scan would be 5 years hence until age 81, at which point scans would be done every 2 years until cryopreservation ensues.

Figure 26: Proposed algorithm for Deanimation Screening Scan intervals and actions.

These scan intervals are arbitrary and will no doubt need to be refined over time as experience is gained. Intuitively, it seems that there should be a relationship between scan intervals and increasing age, and it is possible to configure scan intervals based on things like increasing risk of SCA or terminal illness with age. However, until some real world experience is gained, a conservative approach which minimizes costs and maximizes the opportunity for benefit, seems best. There are lots of programmers, mathematicians and similarly qualified people in cryonics and if any are interested in working with me, I am interested in generating scan interval algorithms based on the rising risk of disease and death with age (if you are interested, contact me at

Going it Alone?

If a decision is made to proceed with DSSing on an individual basis, there are a number of important things to keep in mind and to do:

* Do consider carefully the possible impact this decision will have on you and on your family. In fact, give some thought to discussing this with your spouse or significant other before moving ahead.

* Do select a good imaging center with competent and caring staff who can give you good counsel about the procedure and the results. Imaging centers that offer full body scans are often used to counseling patients: make sure the one you select is a good one. Talk with the staff about your concerns before you commit to being imaged.

* Do explain to the radiologist who will interpret your images that you are having a baseline scan done and you only want to know if there is unequivocal pathology present that requires immediate or urgent medical intervention. If you can’t get that assurance from him, ask for your results only in writing on the same disk on which your scan is written.

* Don’t look at your scan or the written report that accompanies it. If you have a reliable and willing CO, send a copy to them and ask them to send you the results a year from when they receive the media with the images and the report on it. Duplicate CDs are typically made and given upon request at no charge, or for a small fee at the time you are imaged, or when you come for your results. Bring your own media to save money!

* Do provide a copy of the disk with the scan on it to your medical surrogate and to anyone who is on you ICE (in case of emergency) contact list on your mobile phone. The reason for doing so is that, should you experience SCA during the blinded waiting period, the scan may still save you from autopsy if it documents the presence of CAD, or some other pathology that could have caused your sudden and unexpected deanimation.

* Don’t  rely on the DSS to keep you out of trouble, or to reassure that everything is OK, should you develop serious health concerns. Just because a scan shows no indication of pathology does not necessarily mean that there is none. If you have signs or symptoms that would have prompted medical attention absent scanning, act on them in the same way after scanning. Let your physician decide if the scan is significant in the context of any illness or concerns.

* Don’t forget that the scan intervals are 5 years and that is more than enough time for serious disease to develop. Indeed, the 5 year window is a long one, especially where cancer is concerned. A DSS is not a health promotion or a disease prevention program. It’s primary purpose is to let you know you are terminally ill, not to assist you in avoiding that eventuality.

* Do know that if you have atherosclerosis, “vasculopathy” and you want to monitor progression of the disease, your scan intervals will have to be much shorter than 5 years – probably 6 months to 1 year, depending upon the severity, your response to medical intervention, and so on.

Economies of Scale?

Medical imaging is a highly competitive, non-monolithic industry consisting of many operators, large and small, both independent and institutionally affiliated. Such market environments inevitably encourage the drive to survive, and thus typically offer the discriminating consumer the opportunity for real bargains. I made a number of calls to imaging centers around the US and discussed the possibility of group discounts and “scan plans” wherein members of an organization or group, even just a group of like minded individuals, could get deep discounts on scans. The majority of centers I spoke with were receptive to this idea, and several discussed specific numbers which were anywhere from 20% to 60% lower than their standard walk-in fee.

Thus, it should be possible for groups of cryonicists in a given geographical area to make arrangements with a local imaging center for scans. The same was also true when I inquired about group or institutional discounts for carotid and abdominal ultrasound screenings, with the difference being that in some cases, prices went from ~ $350 per screen to ~ $60 per screen, providing the group could be scheduled for the same time and place.

The Pre-Cryopreservation Baseline CT Scan

Figure 27: A hypothetical pre- and post-cryopreservation  CT cerebral angiogram. The post-perfusion image would be obtained by administering radiocontrast agent(s) into the perfusate immediately, or shortly before discontinuing cryoprotective perfusion, prior to deep cooling to storage temperature.

If it is at all possible, a final vital CT scan of the head (at least) should be done as close to the time of cryopreservation as possible. This scan should be done with contrast and with no concerns about clinical radiation dose limitations, since the member will be terminal. The objective of this scan is to document, in as much detail (highest resolution) possible, the morphology of the brain and its vasculature. The imaging technique used should be one that optimizes resolution of the cerebral angiogram. The reason for making these images is that they should allow for many important determinations about the quality of initial stabilization and cryoprotective perfusion and cryoprotectant distribution in the brain to be made, at leisure, during the period the patient is in storage.

If contrast agent(s) is injected into the perfusion circuit shortly, or immediately prior to the discontinuation of perfusion, it should be possible to obtain a post-vitrification angiogram, which in turn should allow for evaluation of cerebrovascular patency, as well as assist in determining the anatomical landmarks within the cryopreserved tissue. It should also be possible to add other kinds of tracers to the perfusate, which might allow for quantification of regional distribution of cryoprotectants, or of other molecular species of interest not only within the brain vasculature, but within the brain parenchyma, as well. Again, the presence of a baseline pre-cryopreservation scan will likely be of great importance in allowing accurate interpretation of post-cryopreservation images.

This scan must be a CT, as opposed to an MRI, since MRI scans are unobtainable in deep hypothermia, or in the solid state.

Radiation & Risk

When the mass media talk about the “risks” from radiation associated with CT scanning, the first question that should spring to mind is, “Risks to who?” Sensitivity to ionizing radiation varies based on the cell age and mitotic cycle, and what this means in practical terms is that the younger you are, the greater the risk radiation presents to you.  Children thus have a much higher relative risk when compared to adults due to their rapid cell division and cell differentiation rate.

Figure 28: The risk of developing cancer as a result of radiation exposure is strongly age dependent and decays dramatically as people age. By the time an individual is in his 60s, 70s or 80s, the risk of neoplastic disease from medical imaging becomes negligible. Adapted from ICRP Publication 60 (1990).

Table 1: Nominal Risk for Cancer Effects *
Exposed population Excess relative risk of cancer
(per Sv)
entire population 5.5% – 6.0%
adult only 4.1% – 4.8%
*relative risk values based on ICRP publications 103 (2007) and 60 (1990)


Table 2: Relative Radiation Level Scale
Relative Radiation Level

Effective dose range

None 0
Minimal Less than 0.1 mSv
Low 0.1 – 1.0 mSv
Medium 1.0 – 10 mSv
High 10 – 100 mSv
* Adapted from American College of Radiology Appropriateness Criteria, Radiation Dose Assessment Introduction 2008

These data also demonstrate that you cannot simply use the average relative risk shown in Table 1 to estimate the increased incidence of cancer due to radiation exposure. In order to do this analysis correctly, you need take into consideration the age of all individuals in the irradiated group. For instance, a man of 80 has a life expectancy of about 8 years, versus 33 years for a man of 45. Thus the risk to individuals over the age of 70 is, for all practical purposes, essentially nil. Table 2 illustrates what the  American College of Radiology considers minimal to high radiation doses in “absolute” terms.


Table 3: Average Effective Dose in CT
Exam Relative Radiation Level Range of values (mSv)
Head 0.9 – 4
Chest (standard) 4 – 18
Chest (high resolution,
e.g., pulmonary embolism)
13 – 40
Abdomen 3.5 – 25
Pelvis 3.3 – 10
Coronary Angiogram 5 – 32
Virtual Colonoscopy 4 – 13
Calcium Scoring 1 – 12

This is why there is an increase in the relative risk values for the “entire population”  if children are included in that evaluation. However, even a quick glance at Figure 28 (above), where the estimated lifetime risk that radiation will result in cancer (carcinogenesis) is presented relative to the person’s age, shows that children have a 10% – 15% lifetime risk from radiation exposure, while individuals over the age of 60 have minimal to no risk (due to the latency period for cancer and the person’s life expectancy).  The accepted latency period is, by the way ~ 10 years.

Table 1 shows the relative risk of developing cancer per sievert (Sv) unit of radiation exposure. Tables 3 and 4 provide some comparison benchmarks of radiation exposure both in relative terms (low, medium, high) and in terms of common, specific medical imaging procedures used in regional CT.

So, let’s put this information in the context of a cryonicist wishing to reduce his risk of unexpected deanimation. The protocol being proposed here assumes a baseline scan at age 45 for males (50 for females) which, if free of any indication of ongoing morbid processes, is to  be repeated in 5 years, at age 51. If than scan is negative, subsequent scans would be performed at intervals of 5 years (if negative) until age 81, at which time the scan interval would decrease to 2 years. If we assume a lifetime cancer risk of approximately 1 in 1000 and a total of 7 scans  until age 81, at which point any further risk from radiation exposure becomes irrelevant, we might expect to see an increase in the lifetime risk of cancer from approximate 33% to 34%.  Even if the number of scans were more than doubled to 20; one per two years during the interval between age 50 and age 80, the lifetime risk of cancer would increase at most to ~ 35%.[1] This of course, assumes that all DSSs are CT, as opposed to MRI.

Table 4: Some Exposure Risks for Comparison

Activity/Exposure mSv/year
Smoking 30 cigarettes a day 60–80
New York-Tokyo flights for airline crew 9 .0
Average radiation dose for Americans 6.0
Dose from cosmic radiation at sea level: 0.24


These risk calculations are based on the linear no-threshold (LNT) model of radiation risk.  This model assumes that the carcinogenicity of radiation is proportional to dose, even down to the lowest levels.  No one really knows how carcinogenic low-dose radiation is, because the carcinogenicity of low doses is so small that it’s practically impossible to measure. The official position of the Health Physics Society is that quantitative estimates of risk for doses below 50 mSv per year (100 mSv lifetime) cannot be made.[2]


As useful aside, if you are interested in the progress being made in medical imaging, I would highly recommend the blog Magnetic Resonance Imaging: To See and Be Amazed: The site contains many beautiful images and is a treasure trove of information on both the mainstream progress, and the esoterica of MRI

 Appendix 1

Appendix I: Specimen Protocol for Whole Body MRI Examination to Predict Early Deanimation

Table A-1: Protocol for a whole-body MRI examination for atherosclerosis and colonic polyps. The total examination time (“in-room time ”) is approx. 60 min. SE: spin-echo sequence; TSE: turbo spin echo sequence; CA: contrast agent; FLAIR: fluid-attenuated inversion recovery sequence; HASTE: half-Fourier single-shot turbo spin-echo sequence; true FISP: true fast imaging with steady-state precession

A protocol for a comprehensive examination, not only of the vascular system, is presented as follows (Table A-1). Due to the systemic nature of atherosclerosis, a specific screening protocol has to demonstrate high accuracy in the detection of vascular changes over several regions of the body. This includes the cerebrovascular system with its extracerebral and intracerebral arteries, as well as the parenchyma supplied by these vessels. It is really rather difficult to predict cerebrovascular disease; only 26–50% of patients with a peripheral vascular occlusive disease (PVOD) have a cerebral component [79, 80]; many patients with a vascular disease are however only diagnosed once they have become symptomatic [1].

The screening protocol for atherosclerosis also includes the vascular examination of the aorta, supraaortal branches, visceral vessels, and the periphery. The possibility of imaging all these vessels in a single, brief examination has significantly changed the diagnostic procedure in centers having his facility. Finally, the heart should be examined. Even though the examination may often “only” be able to look for wall motion disorders and previous cardiac infarcts for reasons of time pressure or the lack of suitable sequences, even this provides important information, since the rate of unknown cardiac infarcts/unidentified CHD is not inconsiderable [2].

The whole-body MR angiography was performed with the aid of a system-compatible “roller-mounted table platform” (back then the newer systems with integrated whole body image acquisition were not yet available) [3]. This platform allows acquisition of 5–6 three-dimensional angiography data sets following a single administration of contrast agent using the “bolus chase” technique. Besides the possibility of now covering a field of view in excess of 180 cm without repositioning the volunteer, an advantage of this system is the use of surface coils, which, thanks to their higher signal-to-noise ratio, deliver significantly improved image quality compared to the body coil integrated into the scanner.

Heart imaging involves an axial T2-weighted “dark-blood” sequence to produce a morphological overview; this is however extended in the craniocaudal direction to include the entire lung. Images of this type are very sensitive for the detection of focal lung nodules [4].

Functional imaging with fast gradient-echo sequences (T2/T1 contrasts are most informative), as well as late enhancement sequences using inversion recovery sequences to optimize the contrast of infarctions versus healthy myocardium, are acquired in several short and long axis sections. Here, late enhancement imaging uses the intravenous contrast agent previously applied for MR angiography, and repeated administration of contrast agent is not required.

In the last part of the whole-body MRI, attention is then turned to malignomas, and MR colonography is performed. Colon carcinoma, as the second most frequent malignant cause of death after bronchial carcinoma, is the special focus of attention. A three dimensional T1-weighted gradient-echo sequence is acquired following spasmolysis and rectal enema [5].

Much Less Than Half a Chance Part 3

How to avoid autopsy and long ‘down-time’

(ischemia) ~85% of the time!

By Mike Darwin

Removing a Central Objection to Cryonics

In case you missed it, what I just said in that slim paragraph at the end of the preceding part of this article has profound implication because it has the potential to remove what is unarguably one of  the largest and the most rational objections that there are to cryonics. That objection is that roughly two-thirds of those who have made cryonics arrangements will not be cryopreserved under good conditions, and that half of all those signed up will be cryopreserved under very adverse conditions, such as autopsy or long (greater than 12 hours) post cardiac arrest delay. The recent advances in non-invasive medical imaging I’m about to discuss here offer the opportunity to we cryonicists to make many, if not most such losses all but unnecessary.

Figure 17: False color CT 3-D reconstruction of a patient’s intracranial arterial vascular tree. The orange-red, cheery shaped anomaly behind the right eye is a large aneurysm. The brain and other intracranial soft tissues have been digitally subtracted to facilitate a complete and unobstructed view of the patient’s arterial vasculature.

The image that you see in Figure 17 is now a perfectly pedestrian medical image that can be obtained from a garden variety CT scanner available at most diagnostic imaging centers in mid-sized cities anywhere in the world. This particular image has the brain, the soft tissue and everything digitally subtracted from it but the patient’s arterial tree and skull. The cherry shaped protrusion on the right is an aneurysm which, if were to rupture, could cost the patient his life or leave him profoundly disabled.

Figure 18: Many brain aneurysms can be treated non-surgically by passing a very thin platinum wire within the aneurysm where the wire coils up to form a yarn-like ball inside the weakened, ballooned-out area of the vessel wall. A clot subsequently forms around the coil and the vessel eventually closes off the opening to what was once the aneurysm.

Fortunately, there is a procedure  called “coiling” (Figure 18) which allows most such aneurysms to be successfully treated. Sadly, very people with brain aneurysms know that they have one until it ruptures – by which time it is almost always too late treat it effectively.

Scan Your Troubles Away?

The question logically arises, “Why not look inside everyone’s head if we have the technology to do so? Wouldn’t that allow us to identify not only the people who have aneurysms they don’t know about, but also everyone who has a tumor, or a narrowed coronary or carotid artery, or a gallstone, or anything else wrong with them that they don’t know about? In fact, why not scan their whole bodies and see if anything is amiss? Wouldn’t that allow us to nip most slowly progressing degenerative diseases in the bud?”

The answer to that question is a qualified “Yes and no.” The first and most important qualification to consider is the very substantial difference between them and us. They are going to die and, hopefully, we are not. Once you are content to die, it doesn’t really make a great difference exactly how it happens and it certainly doesn’t make any difference what happens to you afterwards. They will pay exactly nothing to avoid laying around dead for x-hours, or to avoid being autopsied. We, on the other hand, will pay something. That is a huge divide, because, as it turns out, the first and greatest barrier to such universal screening using CT and/or MRI is its adverse cost to benefit ratio.

Figure 19:  The rapid advance of computing and the high demand for ever more sophisticated medical images has driven the cost of 3-D CT and MRI scanning down to ~ $200 for a head scan $800 for a whole body scan.

While there are many CT and MRI machines, they are kept adequately busy, or perhaps just a little less busy than some of their owners would like, imaging sick and the worried well or hypochondriacal people. If the entire population, or even some modest fraction of it were to suddenly present for imaging, the system would crash. CT and MRI machines are very expensive and while the cost of scans has dropped dramatically, they are still not free. On the macro-level, governments, insurance companies and economists are constantly struggling to determine which therapeutic and diagnostic interventions offer the best return for the money invested in them.

The Problems of Bite Back and VOMIT

Surprisingly, information obtained from diagnostic tests can sometimes not only fail to yield any benefit, in which the case the money spent on the test is wasted, they can also cause harm. A recent example of this, much in the news, is the Prostate Specific Antigen (PSA) test used as a screening tool for prostate cancer (Figure 20). ( The problem with the PSA test as a screening tool is that to be effective in that capacity it requires a fairly long baseline, a good deal of contextual information (the patient’s race, family history, medications, and so on) and it requires good clinical judgment as well as a ‘patient’ patient.

Figure 20: It was anticipated that the PSA test, used as a screening tool for prostate cancer, would significantly reduce both the morbidity and mortality from the disease. It has so far failed to do so.

A single high PSA reading, or even several, may mean nothing. Most often it is the trend, rather than the absolute number; this is particularly true for black men.  In short, it’s a test that takes a lot of time and thought to interpret and use well and as such is probably not well suited to mass screening where a “yes” or “no” answer is sought before proceeding to costly, invasive and possibly injurious further evaluation.  Yet another problem is that even when prostate cancer is found and treated, it turns out that very few lives are saved because most of those cancers are slow growing and in men who will die of something else before the cancer kills them. Thus, the cost to benefit ratio of the PSA is being questioned, not the least of which because it causes many men to suffer and even die from treatments from which they did not benefit!

This is very much where medicine is today with respect to the “medical imaging singularity.” While it is possible to “look inside” just about everybody, the cost to benefit ratio for the health care system and for the “man on the street” would not justify it. In fact, it would be a medical catastrophe.

To understand why this is so it is necessary to understand three things. The first and most important of these is something called VOMIT, which is a very serious form of bite back associated with our new found ability to see inside patients with increasing exactitude. VOMIT stands for Victim of Medical Imaging Technology and refers to patients who suffer unnecessary interventions for abnormalities observed by imaging or other investigational technology, but which were not found during surgery or subsequent invasive diagnostic interventions. (Hayward, 2003) Here, I will go further and extend the definition of VOMIT to include any diagnostic finding which result in a diagnostic or therapeutic intervention which is not cost effective or causes harm to the patient. That is a very important caveat and tall order to fill, as we shall soon see.

The second is the relatively straightforward one of the ratio of the dollar benefit of resources expended to dollar benefit returned in years of productive life saved as a result of the intervention. Even in cases where early diagnosis saves lives, such as in breast cancer screening, the economic returns are equivocal. It is also often the case that “early” diagnosis with existing imaging technology is still not early enough to cure the disease. As a result, the patient suffers a longer, more miserable course of treatment and the healthcare system is subjected to greater expense with no return.

The third is the problem of information overload and it is somewhat related to VOMIT. The truism that a picture is worth a thousand words is probably a vast understatement. A single 3-D medical image contains a vast wealth of information – information which has heretofore been unavailable to both the clinician and his patient.  This might seem like a good thing, and in the long run it will be, but for now, and for a long while to come the details of the landscapes being revealed will, to a great extent, be terra incognito.

The Danger of TMI

When advances in microelectronics allowed for 24-hour ECG monitoring in the 1970s,  it became possible for clinicians for the first time to see the beat by beat electrical activity of their patients’ hearts for up to a day at a time, or longer. Prior to that, they were limited by the enormous quantities of paper tracings that would be required and the need to confine the patient to the clinic or laboratory. Now, with the advent of the compact and mobile “Holter monitor,” it was possible to capture the patient’s ECG data continuously under ambulatory, real-world conditions (Figure 21). Physicians were awash in a veritable sea-tide of data!

Figure 21: The Model 445 Mini-Holter Recorder which was released in 1976 allowed clinicians for the first time to “see” their patients’ ECGs under real-world conditions and for prolonged periods of time.

The problem was , they assumed, quite understandably, that they knew what it all meant. After all, doctors had been looking at patients’ ECGs for decades in their offices, in hospitals, at bedsides in homes and in physiology laboratories. They knew how to read  an ECG! So, when they discovered that some of their patients had periodic bouts or “runs” of very worrisome arrhythmias, they did the prudent and rational thing – they treated them for these arrhythmias with medications. Unfortunately, the result was the opposite of that expected; a significant increase in morbidity and mortality in these patients, because it turns out that in a subpopulation of healthy people, those arrhythmias were benign and not indicative of any health problem.  Thus, misinterpretation of the “same” information they were confident in dealing with in small chunks, presented in bulk and in a different context, was one of the unforeseen and arguably unforeseeable bite back consequences of Holter monitoring technology. (Harrison, 1978)

The Last Heart Attack?

If you assemble and then read over the Alcor case summaries of the last 40 years it is impossible not to be shocked by the seemingly high incidence of sudden and unexpected cardiac arrests. Because my data set is incomplete for Alcor, I can’t be definitive, but the number seems to be somewhat higher than for the same subpopulation of people from the general population (white, middle class, etc). Until, that is, you consider that most cryonicists are male. So, as you read accounts of cryonicists in their 40s and 50s arresting while scuba diving, while taking a nap or watching television, in part what you are seeing is selection bias at work. The point is, no one ever died of “sudden heart disease” a “sudden aneurysm” or, for that matter “a sudden cancer.” These are degenerative disease that takes years to decades to develop. While still difficult to detect in their nascent stages, their terminal lesions are usually very visible many months and sometimes for even for many years before they end lives.

Figure 22: Coronary artery calcium scoring using computed tomography and carotid intima media thickness and plaque using B-mode ultrasonography offer the prospect of detecting almost all coronary artery disease before it reaches the stage where it can cause a heart attack or sudden cardiac arrest.



There has been a great deal of media attention lately to an initiative called SHAPE; The Society for Heart Attack Prevention and Eradication,  which aims to all but eliminate heart attacks by combining CT of the heart to obtain a “myocardial calcium score” (a powerful risk predictor of heart attack)(Figure 22) and carotid intima media thickness and plaque using B-mode ultrasonography as part of a three step program to eliminate heart disease. The next two steps in SHAPE’s plan are a “polypill” combination of blood pressure and anti-atherosclerosis drugs and finally, perhaps, a vaccine. A similar “Last Heart Attack in America” initiative focused on coronary scanning along with dietary interventions to reverse atherosclerosis has been the focus of a feature length documentary on CNN in which former US President Bill Clinton is prominently  featured as a spokesman and advocate. The common ground of these two initiatives is that almost no one dies of a heart attack without there being  glaring evidence present in their hearts years before the infarct occurs. It is only necessary to look for it!

There can be no question that as imaging technology evolves, and as medical acumen catches up with what is available, that such imaging will become a routine part of any checkup  for patients whose age and risk profile merit it (and eventually, if they live long enough, that means most patients). As it stands right now, if you are a middle aged man or woman with a significant risk profile for heart disease, and you have a heart attack, it’s my personal opinion you have ample grounds to sue your physician for negligence.  Right now, that’s just my opinion, so it doesn’t count for anything, but the point is that sooner or later this, or a better coronary imaging modality is going to become the standard of care and heart attacks will become a rare event – a thing of the past – a relic from a time when doctors couldn’t see inside of you.

Ultrasound Investigations

There are cheaper, simpler and completely risk free ways (in terms of radiation) to  find out whether you have atherosclerosis or not.  The most predictive of these for money is the carotid ultrasound (CUS) test.

Figure 23: The carotid ultrasound scan is  a simple, non-invasive diagnostic investigation that employs sound waves to create an image of the two large blood vessels in the neck that supply most of the blood to the brain. If there is a buildup of plaque or a thickening of the limning of these two arteries the person is at increased risk of stroke and there is a high probability that there is also systemic atherosclerosis present. If there is evidence of severe narrowing of one or both of the vessels, then it becomes urgent that medication and possibly surgery be used to correct the condition in order to avoid the likelihood of a crippling or lethal stroke.

This simple, non-invasive test takes just a few minutes and uses ultrasound waves to image the carotid arteries and the blood flowing through them (Figure 23). If there is thickening of the arterial wall, or plaque present, then it is a virtual certainty that the person has systemic atherosclerosis and warrants a more extensive workup. This test is often also “packaged”  with a quick “look-see” at the abdominal aorta also using ultrasound, to rule out the possibility of an abdominal aortic aneurysm – something that is more common in smokers once they reach middle age, and beyond.

If you shop around diligently, the cost a CUS can be as little as your transportation costs to the health fare or community center where it is being offered, often as a “loss leader” by health care providers or medical imaging companies seeking more remunerative business opportunities (if they find something amiss during the CUS).  The cost of such an evaluation can range from as little as $60, to as much as $380.

A CUS is ideal for people on a budget and for those under age 45 with no history of heart disease, cancer or other pathology or risk factors that might put them at increased risk of sudden cardiac arrest.

Why Full Body Scans?

Figure 24: The full body CT or MRI scan is often offered as “add-on” to the complete or the “executive’s” physical. Many imaging centers offer these scans without the need of the patient’s person physician prescribing the scan using their in-house radiologists to write the order for the test.

 Put simply, there is no substitute for seeing, or to put a new twist on an old adage: a picture is worth a thousand medical tests. While the origins of all of the degenerative diseases that kill us are at the molecular level, mostly we die as a consequence of the macro-level changes they inflict on our bodies, even if the coup de gras is rooted in the action of things like adhesion molecules and inflammatory pathways; as is the case with most heart attacks. It is the large, easily “seen” bulges of aneurysms, masses of plaque or tumor that kill, and these almost always take years to develop. What this means practically is that, with a few exceptions, aside from suicide, homicide and accident, virtually no one has to die – or to deanimate without plenty of advance warming. The implications for cryonics are as obvious as they are profound.

Much Less Than Half a Chance? Part 2

How to avoid autopsy and long ‘down-time’

(ischemia) better than ~85% of the time!

By Mike Darwin

Ischemia: The Problem of “Long Down Time”

 Almost every cryonicist I’ve ever spoken with envisions his cryopreservation will occur under ideal circumstances. He will be diagnosed with  some vague and ill defined terminal illness, bravely decide to end futile treatment and then enter hospice with a team of skilled and caring cryonics personnel at his bedside. He will nap, read, watch TV, and then, near the end, nod off surrounded by loved ones as the cryonics personnel hover nearby. This may not be the most attractive picture in any absolute sense, but it is certainly as reassuring a one as it is possible to find in contemporary cryonics. And while many, or even most cryonicists may find this scenario credible, much of the rest world doesn’t.

 Figure 10:  Approximate U.S. distribution of predictable deaths by cause based on 2004 data. Note that ~57% of all deaths occur sufficiently suddenly, or under circumstances such as accidents, which preclude standby or other cryonics stabilization measures. Chart derived from data: [National Vital Statistics Report, Volume 53, Number 5 (October 2004)]. This data may be compared to the data in Figure 10 to see how closely the US national incidence of sudden and unpredictable death map that of Alcor’s experience (Figure 11).

One likely reason for the scarcity of biomedical people involved in cryonics is that their actual, day-to-day experience is at sharp odds with the scenario I’ve just laid out above.  In countless hours of both focused and casual conversations with such individuals, what emerges is a sense of incredulity about the reversibility of the damage these professional and technical people witness as a part of their duties caring for the very old, and the critically ill dying; not to mention that large fraction of people who die suddenly and without warning, end up as DOAs in the emergency department or coroner’s cases. Regardless of whether their opinions prove the valid ones, we are clearly failing to communicate to them and to the community at large, an experience of cryonics which is not so biomedically adverse.

To do that, it is first necessary to move beyond  anyone’s scenarios or suppositions and evaluate the reality of what is actually happening to the patients we cryopreserve. That turns out to be a hard thing to determine with any degree of precision, because none of the cryonics organizations maintain any kind of statistical database on their members’ cryopreservations. How many cryopatients have dementia? How many were autopsied? What is the mean ischemic time from cardiac arrest to the start of cardiopulmonary support (CPS)? How many patients have ischemic times of 2-5 minutes, 5-10 minutes, 15-30 minutes, 12 hours, 14 hours, 5 days? What is the mean age at cryopreservation? [Absence of data on this last question I find particularly amusing in a group of people supposedly preoccupied with longevity and "life extension": how long are they living, on average?]  There is currently no way to tell.

There is not even any way to determine the age, gender, or any of dozens of other potentially critically important demographic details that are, or could be vital in assuring quality cryopreservations, reducing ischemic times, or reducing known iatrogenenic events. A concern of mine for onto three decades now is that we have no way to spot adverse epidemiological events that might be associated with our unique dietary supplement or other lifestyle practices. Perhaps most incredibly, there are no written criteria, however arbitrary, to assign any degree of quality, or lack thereof, to the cryopreservation a given patient has received (let alone that a given Cryonics Organization (CO) provides, on average). This had lead to what has become known as “the last one is always the best one” to date rating system, wherein each case that is not either an existential or an iatrogenic disaster, is pronounced by the staff who carried it out as, “the best case we’ve done so far!”

We cryonicists may be in some kind of willful, data free fog about what our situation is, however, it’s a safe bet to assume that most of the rest of the world, based on their own professional and personal experiences, are not so ignorant. The first step towards a solution is to understand the scope and severity of the problem by getting reliable numbers. While that is not easy to do, the Alcor Life Extension Foundation does maintain a crude, if incomplete accounting of all the patients they have placed into cryopreservation: A cursory analysis of this yields the following breakdown. Even basic data such as cause and mode of death are missing from ~20 of the cases listed there – these have necessarily been excluded from the analysis below.

Figure 11: A major hurdle to evaluating quality in cryonics operations is the lack of any outcomes (e.g., reanimation followed by evaluation) or of any surrogate markers or scoring systems to serve as evaluation tools to determine not only the quality of cryopreservation care being given, but also the objective neurocognitive status of the patients when they enter cryopreservation. For the purposes of this analysis very crude criteria were used to assess the quality of the patient as a finished product at the end of cryopreservation. These were normothermic ischemic time between cardiac arrest and the start of CPS, catastrophic peri-arrest brain injury such as an intracranial bleed followed by prolonged cerebral no-flow before pronouncement of medico-legal death, very long warm ischemic times (> or = to 12 hours) and autopsy.

Using the criterion of “minimal ischemia” (≤15 minutes)[1], 48% of Alcor’s patients are cryopreserved under these conditions (Figure 10).  Thirty-nine percent of their patients suffer long ischemic periods of 6-12 hours or more (mostly as a result of SCA and UDA); and 13% suffer very long periods of ischemia (> or = to 24 hours) which are not currently preventable, or which conclude in autopsy prior to cryopreservation.  Put more cogently, you have less than a 50% chance of being cryopreserved (with Alcor) under conditions of minimal ischemia. While this number is discouraging, it is spectacular when compared to the Cryonics Institute, where it is somewhere in the low single digits.


Figure 12: The graph above is the same as in Figure 11, with the difference being that the losses have been expanded to include those that would be expected if the population wide incidence of end-stage, GDS-7 dementias were imposed on all the groups. The result is that percentage of patients who might reasonably be expected to have both minimal ischemia and no pre-cryopreservation GDS-7 dementias drops to just 26%.

But once again, these numbers are misleading if the criterion is cryopreservation under minimal ischemia conditions, because they do not take into account the number of patients who enter cryopreservation with dementia, or severe brain injury due to stroke, other neurovascular disease, or massive head trauma. If only dementia, at the current incidence for the general population is factored into the analysis, then the picture becomes considerably more bleak, as can be seen in Figure 10, with only 26% of  Alcor cryonics patients being preserved with relatively intact brains under reasonably good conditions.[2]

Impact of the BDDs on the Likely Survival of Personhood


Figure 13: The effect of advanced Alzheimer’s Disease on the macroscopic appearance of the brain is evident when coronally sectioned brains from an AD (R) patient and a healthy person in their mid-20s (L) are compared side by side.

Deaths from AD are typically deaths from end-stage AD, which usually implies severe global destruction of both cerebral hemispheres (Figures 13 & 14) on both a macro and microscopic level. Death due to AD is a prolonged process (~8 years from diagnosis to death), and the neurological deterioration that occurs as the disease progresses is often scored using the global deterioration scale (GDS) of primary degenerative dementias, which ranges from 1 (least) to 7 (worst) in severity. GDS scores in excess of 5 are associated with major loss of macro- and micro-scale brain structure and will be assumed here to represent serious compromises to, or the destruction of personhood.

Figure 14: The histological appearance of the brain in AD is shown in panels b and c above. In many areas of the brain there is virtually complete loss of the neuropil; the synaptic weave that interconnects neurons which can be seen in its normal state in c, the panel at the far left. The majority of the neurons and many of their supporting glial cells have died and been scavenged by macrophages and histiocyytes.  There are abundant deposits of proteinaceous plaque containing the  neurotoxin protein beta amyloid neurofibrillary tangles which are the remnants of neuronal long processes such as axons and dendrites. The extent and uniformity of the changes seen above varies from patient to patient during the course of the disease, but becomes increasingly uniform throughout both hemispheres of the cortex the longer the patient survives with a GDS score of 7 (end stage dementia).

A Deanimation Warning Device?

Figure 15: The medical imager as a deanimation prediction device?

 In his 1939 science fiction story Life-Line,” Robert Heinlein envisions a device that can predict, with considerable precision, when a person is going to die. While none of us cryonicists wants to die, most of us could certainly profit from knowing when we are going to deanimate. Better still would be also finding out how to postpone our cold dip in liquid nitrogen for a while, if it was possible to do so.

Many cryonicists will be familiar with this graph of Ray Kurzweil’s showing the impending arrival of the singularity (Figure 16).

Figure 16: Ray Kurzweil’s graph showing the exponential increase in neuro-image reconstruction which has occurred largely as a function of the exponential growth in computing capacity since 1970.

Well, if you are a cryonicist, I’m here to tell you that insofar as non/minimally-invasive medical imaging is concerned, the singularity is here.

From the earliest days of medicine physicians have desired one thing almost above all others and that is to possess the power to peer into their patients bodies and observe the goings on there. Since the discovery of x-rays by Wilhelm Conrad Röntgen in 1895 (Crane, 1964) there has been steady progress towards the satisfaction of that desire. The development of contrast media, endoscopy, computerized axial tomography (CAT or CT) scanning and magnetic resonance imaging (MRI) scanning have allowed increasingly exact and impressive images of the interior of the living body to be made.

However, a number of serious limitations have, and to a great extent still do prevent the full realization of the physician’s idealized desire to see inside his patients at will. Those barriers are field, dimensionality and point of view, as well as resolution, color, contrast and the dollar cost of the imaging.

In the case of CT and MRI those barriers have been breached to such a degree that it is now possible for cryonicists to be able to determine with a very high degree of accuracy and precision both of what and when they are going to experience medico-legal death. A corollary of this is that in many cases it will be possible for them to avoid what would have otherwise been an unavoidable very long period of ischemia and quite likely a medico-legal autopsy  as well.

End of Part 2

[1] This criterion is being very generous because it assumes that all interventions that begin within ~15 min of cardiac arrest are effective at preventing further ischemic injury. This is not the case for most cryonics patients where external cardiopulmonary support is not effective at restoring adequate perfusion and gas exchange, core cooling may be delayed by several hours, and cold ischemic times may be in the range of 12 to 24 hours.

[2] Again, using the very generous criteria of assuming that all CPS is effective CPS and that no iatrogenic events compromised the quality of the cryopreservations.

Much Less Than Half a Chance? Part 1

How to avoid autopsy and long ‘down-time’

(ischemia) better than ~85% of the time!

By Mike Darwin

It’s easy to concentrate on the biggest and most obvious reason that cryonics hasn’t attracted wider acceptance, principally the fact that it doesn’t work “yet” and it will be a long time before we know if does. But there’s a clue to another capital reason for its slow adoption which is to be found in the failure of cryonics to attract much enthusiasm or activism within its own ranks. Why is this?

I believe a central reason for this failure is that cryonics, even as it is currently configured and accepted by those who embrace it, performs dismally. Everyone seriously involved with cryonics is painfully aware, either consciously or subconsciously, that cryonics is at least a two tier lottery. Sure, everyone knows that we’re taking a “chance” on being recovered in the future by being cryopreserved in the first place. But to even get to that round of the lottery, you have to get cryopreserved, and it would seem material whether or not you are cryopreserved well.

For some, perhaps cryonics is a ritual exercise. As long as there are remains, a freezer, someone to take the money and hang picture on the wall, then you have a chance; and all chances are created equal. Their position seems to be same as that of the millions of lottery ticket holders before the winning number is announced: we all have the same chance at the prize. If that’s your attitude, you can stop reading this right now, there’s nothing more here to interest you – not even in terms of idle entertainment value, because this discussion, from here on out is deadly serious, and brass tacks practical.

 Figure 1: The autopsy rate has declined by half in the United State between 1972 and 2007, although it has shown a slight increase since these data were collected. Source:

As Figure 1 shows, the autopsy rate, which can serve as the ultimate, population wide indicator of a very bad cryopreservation,  constituted 8.5% of all deaths in 2007. That percentage has risen slightly since then and is now at ~ 9%. The situation isn’t quite as grim as it might first appear if you break down the reasons for autopsy and note that 55.4% of autopsies were conducted as a result of deaths due to “external causes,” which means suicide, accident or homicide. If you think you are in a “lower risk” category for these, you may  be right, in which your case your risk may be fractionally smaller. And of course, not all of these autopsies were state mandated: some were requested by the next of kin, or even the decedents themselves. Still, 9% seems a reasonable, overall unavoidable loss number currently confronting cryonicists given the culture we inhabit.

Figure 2: Since the first man was cryopreserved in 1967, the demographics of autopsy have shifted increasingly from the aged to those in younger population cohorts. Source:

If the age distribution of autopsies in the US is examined, the picture gets even more uplifting if you are, or you expect to live in into old age (which is, incidentally, medically defined as 65 years of age, or older). In this age group, the incidence of autopsy has declined dramatically from 37% of all postmortems since 1972,  near the time cryonics began, to only 17% as of 2007.

However autopsy is only one of a number of factors that can and do interfere with  cryonicists achieving “good,” or even “acceptable,”  (forget  ideal), cryopreservations. The other three factors which loom large are sudden cardiac arrest (SCA), unexpected death (UD, which is different than SCA) and brain destroying diseases ( BDDs, or dementias). While Alzheimer’s Disease is the most common of the BDDs, there are others such as Pick’s, Lewy Body, Parkinson’s and the vascular dementias, which together account for 20-30% of all age-associated BDDs.

Brain Destroying Diseases (Dementias)

Autopsy is only one of a number of factors that can and do interfere with  cryonicists achieving “good,” or even “acceptable,”  (forget  ideal), cryopreservations. The other three factors which loom large are sudden cardiac arrest (SCA), unexpected death (UD, which is different than SCA) and brain destroying diseases (BDDs).

 Figure 3: Incidence of dementias as a percentage of all cause mortality in males, females and the United States population as a whole. Prepared from data in the National Vital Statistics Report Volume 59, Number 10 December 7, 2011Deaths: Final Data for 2008: 2008

 Currently, the BDDs in aggregate (including catastrophic stroke) account for ~3.2% of all deaths in the US (Figure 3). However, insofar as cryonicists are concerned, this number is likely to be misleadingly low, because most cryonicists enter cryopreservation at or after age 65, the point at which the incidence of BDDs begin to climb exponentially. (Evans DA, 1990) This number is expected to, and in fact is exploding as a consequence of both the demographic shift due to an aging population in the West and increasingly longer life spans (Figure 4).

 Figure 4: The large increase in Alzheimer’s Disease as a cause of death in the United States is largely a function of the increasing average age of the population and the survival of many additional individuals into advanced old age. Source:


 Figure 5: A breakdown of dementias by type shows that Alzheimer’s Disease accounts for 47% of the total as the sole cause of the dementia and is a major contributing factor in another 28% making it by far the most common pathological mechanism in play as the cause of dementia in the elderly.  [S. Seshadri, S, Wolf, PA, Beiser, A,  Au, RU, McNulty, K, White,R, et al. Lifetime risk of dementia and Alzheimer's disease: The impact of mortality on risk estimates in the Framingham Study. Neurology, 49:1498-1504,1997.]

 Figure 6: Incidence of Alzheimer’s Disease by age cohort in the US population as of 1988.[ Evans D, et. al. Prevalence of Alzheimer' s Disease in a community population of older persons. JAMA, 262:18;2551-6, 1989.]

In the 74-84 age cohort, 19% of that population has AD (exclusive of other dementias) and in those individuals over the age of 85, the diagnosed incidence is 47%. These numbers are almost certainly low, because many of the elderly are who are institutionalized for falls, or other issues not ostensibly related to primary brain disease, go on to develop brain disease in an institutional setting and ultimately have listed as their causes of death, pneumonia, urosespsis, sepsis  secondary to decubitus ulcers, or other causes that escape epidemiological surveillance for AD. Currently, AD is responsible for 2.8% of deaths in white males men aged 65  or older and 4.7% of white males who are 85 years of age, or older. These numbers are expected to triple by the year 2050.

 Figure 7: The incidence of Alzheimer’s Disease rises roughly exponentially with age such that over 1,100 people out of 100,000 aged 86 or older have the disease.

When cryonics was launched in the mid-1960s the problem of BDDs as a threat to the workability of cryonics was not even considered.  In 1967, the year the first man was cryopreserved, the average life expectancy in the US was ~70 years and the problem of dementias was a fraction of what it currently is.  Additionally, comparatively little was known about the pathophysiology of the BDDs at that time, and there was little or no awareness within the cryonics community of their potential to degrade or altogether destroy personal identity, perhaps even years in advance of the pronouncement of medico-legal death. The problem of BDDs and of age-associated destruction of the brain is arguably the foremost biomedical obstacle confronting cryonics in the long term, and it is for this reason that I will return to this topic again later in this article in the context of discussing its early detection, with a brief discussion of treatment, and ultimately, definitive interventions to halt and reverse it.

Figure 8: The Siemens Biograph mCT PET is a positron emission tomography/computed tomography (PET•CT) scanner that enables precise measurement of metabolic processes and data quantification, including the assessment of neurological disease and malignant tissues (resolution and molecular characterization of neoplasms as small 3 mm in diameter). The device can provide quantitative measurements of brain beta amyloid protein burden.

For now, I will note that because AD is by far the most common of the BDDs and because it has a unique pathophysiological feature, a remarkable advance in early diagnosis via noninvasive  computerized tomography (CT) and positron emission tomography (PET) imaging has recently become clinical available. Beta amyloid is the protein found in the plaques characteristic of AD, and there has been intensive research over the past decade to identify radiolabeled tracer compounds that will safely cross the blood brain barrier (BBB) and bind to both beta amyloid and tau proteins. (Barrio 2008), (Black, 2004)  In February of this year, the US FDA approved the Siemens Biograph mCT, a positron emission tomography-computed tomography (PET-CT) scanner capable of not only detecting, but of quantifying  amyloid in the brain. The Biograph mCT has been very well received, and within the space of a few months the machines have appeared in most major cities in the US. The Biograph mCT in conjunction with the recently developed FDDNP, (2-(1-6-[(2-[F-18] fluoroethyl)(methyl)amino]-2-naphthylethylidene) malonitrile) tracer allows for calculation of total brain amyloid burden (Wang, 2004) and visualization of discrete amyloid containing lesions as small as ~ 3 mm in diameter (tracers for tau protein, the other primary pathological protein in AD are currently in the pipeline for FDA approval).

 Figure 9: Top: PET scan of beta amyloid deposits in the brain of a patient with early moderate Alzheimer’s disease appear in red in the image above. The beta amyloid deposits are concentrated, as expected, in the frontal and prefrontal cortices as well as in the hippocampus. Bottom: Beta amyloid distribution in the brain of a patient with early moderate AD (L) versus normal control (R). One important consequence of this imaging is the growing realization of the global range of AD’s impact on the brain. As recently as a decade ago it was believed that the destruction of brain tissues was confined largely to the hippocampus and the prefrontal cortex, especially early in the disease. It is now understood that the histological destruction of AD is widespread and that during the end-stage of the disease few if any areas can be expected to be spared.

Very early detection of AD may turn out to be critical to achieving effective treatment, or even slowing progression of the disease, since significant beta amyloid and tau deposition seem to promote ongoing inflammation and interfere with putative therapeutic drugs. A good example of this is the recent fate (Vellas, 2010) of the investigational drug  tarenflurbil ((R)-flurbiprofen ) which inhibits gamma-secretase, the enzyme that produces beta amyloid AB-42, the species of beta-amyloid that forms fibrillary plaques. (Black, 2008) Unfortunately, the drug does nothing to remove existing existing AB42 deposits, which presumably continue to exert their neuron killing and pro-inflammatory actions.

(R)-flurbiprofen is highly effective in animal models of very early AD and the drug showed significant promise in Phase I & II clinical trials. However, development of (R)-flurbiprofen was dropped when it became apparent in Phase III trials that the drug would likely only be effective in a clinical setting if it its administration was begun before clinical signs of AD developed; in other words, when beta amyloid levels were very low and would be detectable only by testing cerebrospinal fluid or, now with sensitive CT molecular imaging techniques involving the screening of subpopulations of healthy individuals at risk.

This kind of effort and application of technology and pharmacotherapy may not profitable for pharmaceutical companies, but that does not mean that it would be be worthwhile for us cryonicists. (R)-flurbiprofen  is a close chemical relative of the OTC NSAID ibuprofen and it is a metabolite of the prescription NSAID flubiprofen.  (R)-flurbiprofen  is an enantiomer of flurbiprofen (~ 5%  of (L) flubiprofen is metabolized into (R) flubiprofen by the liver after ingestion) which is completely inactive as  a COX inhibitor, and is thereby free of the anti-COX side effects associated with NSAIDS.  Despite it’s lack of both COX-I and COX-II activity, the drug does have strong anti-inflammatory activity by acting through inhibition of NF-κB and AP-1 activation pathways, and this may provide added benefit in controlling the inflammatory processes associated with AD. (Tegeder, 2001)  As an interesting aside,  (R)-Flurbiprofen has also been shown to suppress prostate tumor cells by inducing p75NTR protein expression. (Quann, 2007)

(R)-Flurbiprofen is an example of a drug with considerable therapeutic potential that will almost certainly not see clinical application due to the high cost associated with regulatory burden and the logistical hurdle of needing to start therapy years before symptoms of AD manifest themselves. (R)-Flurbiprofen might also conceivably be useful as combination therapy with  the already FDA approved skin cancer drug bexarotene (Targretin), an antineoplastic, which has been shown to reverse beta amyloid deposition in a rodent model of AD as well as to improve cognitive function. Targretin rapidly cleared beta amyloid from the brains of animals in a variety of models of AD (<2 months) and while it is not a cytotoxic chemotherapeutic agent, the drug has sufficient adverse effects that it would be problematic to administer over a period of years or decades. A combination of short term therapy with Targretin to remove beta amyloid, followed by long term administration of (R)-Flurbiprofen is a possible treatment strategy that would seem attractive to explore. The ability to dynamically monitor beta amyloid levels in the brains of patients undergoing such novel therapeutic regimens, especially outside the confines of the medical-industrial establishment, is yet another advantage of this evolving singularity in medical imaging.

When a Singularity Bites You in the Ass

 How to avoid autopsy and long ‘down-time’

(ischemia) ~85% of the time!

By Mike Darwin



It has taken me roughly 30 years to learn that having the technological capability to achieve some marvelous end is only a small part of the battle to actually achieving it.  This is profoundly true in the world of biology and medicine because, unlike as was the case with “free speech” and “private life,” there was no Martin Luther and no Thomas Paine to definitively divorce these areas of human endeavor from the grasp of the religious moralists, the secular ethicists, and the social busybodies of the earth. The life sciences have yet to have their Martin Luther’s 95 theses nailed to the doors of the places in which this culture’s moral tyrants currently reside. The separation of Church from private life which began with Luther, and of private life from state, which began with the Magna Carta and the US Declaration of Independence, could take us only so far.

Now, we are in an interesting place and time, because never before have potentially lifesaving technologies been being generated at such a phenomenal rate. And yet, they remain outside our grasp as surely and solidly as if there were an impenetrable Prespex wall between them and us. We can look, but we can’t touch.

Beyond our physical inability – or seeming physical inability – to access those lifesaving capabilities, we also pay a heavy price in a different way. Our vision and perspective becomes warped. We literally become unable to see how we might help ourselves, because we have been conditioned to be dis-empowered. We lose the ability to think outside the box and we begin endlessly replaying the failed or marginal strategies that the existing system does allow us to pursue.

However, a close look at our predicament will reveal that that Perspex wall works mostly for the masses – for them – and not for us. If we are careful and clever, we can reach through it and extract much of the technological benefit sitting there. We can do this, but they can’t. Once we understand that, it has the potential to change our perspective on everything in terms of our chances for survival, and for our chances of living productively and in comfort, while much of the rest of world may well pursue a very different path.

That’s what this article, and the ones that follow it, are about. This article is preparatory, it’s a kind of foreplay to prepare you for the powerful penetration of the ideas that are to follow.

Of  Singularities & Hams

Figure 1: Jamón ibérico de bellota is a gourmet ham made from black Iberian pigs fed only acorns during the months prior to their slaughter.

 The first few times it happened, I hardly noticed, and I can’t remember the specifics. But when it really began to annoy me I can  remember, quite clearly, perhaps because I was already in a foul mood and the surroundings were extraordinary. We had been taken out earlier in the day to see the pigs from which the jamón ibérico de bellota is made. The vile, dusty, slobbering and altogether horrid beasts are fed nothing but acorns so that their flesh is rendered especially succulent and flavorful after elaborate smoking and aging. They were moving about with indifferent belligerence, unaware that their kin were to  be on the supper menu late that afternoon. The visit to their quarters made me thankful I did not eat land vertebrates and reminded me uncomfortably of some of my compadres at the Hacienda; the several “Mr. Bigs” who had gathered to discuss the creation of a new cryonics enterprise.

As we sat down to dinner in the courtyard of the Hacienda that evening, I was seated at a table with several middle aged cryonicists and two older ones, (sadly, including myself). It wasn’t long before I was bombarded with the question I would soon find irritating, and eventually come to loathe: “Have you had genomics testing done?”

Figure 2: The courtyard of the Hacienda where my dinner companions assailed me over my lack of diligence in having my genotype analyzed to determine my disease risks.

“And why would I have that done, I asked?” My questioner, an enthusiastic thirty-something, leaned forward a bit and explained to me how rapidly the cost of sequencing DNA base pairs was dropping, and that it was now possible to tell all kinds of things about an individual’s risk for diseases by genotypic analysis.

“It costs only  $200 US; I just had mine done.”

Others began to chime in. Since it was an international crowd, the stories were fascinating and I was content to listen. Some had discovered they had Neanderthal lineage, others had discovered less exotic, but no less unexpected genetic heritage. Finally, the conversation returned to me, the apparent elder statesman and, presumably, the example setting cryonicist at the table: why hadn’t I had my genotype evaluated, and much more importantly, why didn’t I have any plans to do so?

“Look, ” I said, “I think genomics  technology is going to be incredibly valuable. I think its most immediate value is going to be in pharmacogenomics – in determining which drugs work for which individual people and which drugs don’t work, or are actually dangerous for given individuals. A bit later, this technology will likely have real prognostic value. But not now, and not for me. I’m in my early-50s. My relatives are already sick, dying or dead of illnesses that are genetically mediated. I know what my genetic risks are. In fact, from my family history alone, I’ve known what those risks are for roughly 20 years now. Both my parents are now in their 80s, and I have a very good idea of what they are going to die of. And if they don’t die of those things, well, it will be from an accident, an infection or something not likely to be readable in the tea leaves of my genome.

 Figure 3: The Hacienda on the arid Spanish countryside outside Madrid where we took our repast and discussed singularities, past, present and future.

Interestingly, my parents have had every single disease that has also killed their parents, their aunts and their uncles: cancer, hypertension, atherosclerosis, alcoholism, type II diabetes, and Alzheimer’s Disease (AD). I’m pretty sure that AD is going to claim my mother’s life, and I’d say it is probably down to atherosclerosis, and possibly cancer or emphysema, in the case of my father. With the help of modern medicine, my folks have so far dodged all of the other genetically mediated bullets that have been shot at them. So, I know my genetic risks  (and to those I’d add the risk of some peculiar autoimmune diseases in late life are present in my maternal bloodline).

But by far my biggest risks, which would not yet (to my knowledge) show up on any genotypic test are Bipolar-2 Disorder and homosexuality, both of which have a devastating impact on longevity, dramatically increasing the risk of a broad range of pathologies, including cardiovascular disease, cancer, dementia, substance abuse, other mental illness, and all cause mortality. My point is that in most cases where genes influence destiny, you’re best clue is the evolved or evolving fate of your kin – unless you are an anonymous orphan, that is.”

Still, they wouldn’t give up. The implication was that I must have genomic testing. And, truth to tell, I had, and have, no objection to it. It’s not like I am opposed on religious grounds, as if it were fortune telling. “In fact, I think it’s a nifty conversation piece and personally interesting in the bargain. It’s just that I’d have a lot higher priority uses for my $200 in terms of the dramatic medical advantages it could buy me as a cryonicist, if I had $200 to spend on such things! It would make a wonderful Newton Day gift, the kind of thing you’d like, but would never buy for yourself.”

Now that, that statement really set them off! I had thrown gasoline on a fire. Didn’t I know that the exponential decrease in the cost of DNA sequencing constituted a Singularity in biomedicine, one that was, even as were sitting there that very moment, revolutionizing medicine? “Sure.” I said, “But  there are singularities happening all the time. The thing is, most singularities in medicine unfold over a period of decades, and very few individual patients gain benefit from them on the basis of special, unique, or insider knowledge.”

But, I had lost them. They were having none of it, and I wouldn’t be the least bit surprised if I’ve lost you as well. I was irritated and frustrated and I had already lost my temper badly earlier that day. So, I decided to bite my tongue and proceed in relative silence with the rest of the meal. But what I really wanted to say to those gentleman was that, “you wouldn’t know what to do if a medical singularity were to come right up here and bite you in the ass, because it already has!”

One of the (many) reasons the meeting had crumbled was the intransigence of one of the Mr. Bigs, who wanted cryonics with the stipulation that there be essentially no ischemic time. He had his approach to solving the problem which was, well, this meeting was some years ago, and I wonder if Mr. Big is still alive?

It was a strange situation. Mr. Big was clearly not a well man and he knew this to be the case. What I suggested was straightforward, involved nothing either exotic nor illegal and was something that I knew would work, based on the sorry experience of seeing it not work with men exactly like him. I tried to explain to Mr. Big that it was now possible to “simply” look inside of him, from top to bottom, and get a fairly accurate assessment of what his risks were for deanimating in the near future. Given his medical history, which he shared with me,  I also suggested that he have a condition treated which would, probably sooner rather than later, cost him his life, or leave him profoundly disabled. He was having none of that, either!

Instead, a few hours later, here we were seated together at dinner and Mr. Big was extolling the virtues of genomic testing as a way of avoiding premature cryopreservation-  to me.  A true, nearly unalloyed medical singularity had arrived for cryonicists, and for the previous two days they had snuffled and shuffled around each other with same indifferent belligerence of the hogs in the pen nearby who were awaiting their conversion to jamón and their journey away from the Hacienda in someone’s belly. It is at moments like this, which come with increasing frequency, that I sneak a quick look out of the corners of my eyes to see if I can catch a glimpse of some dimple or ripple in the fabric of reality that will clue me into the fact that my life has really been just a joke in very poor taste  – on me.

I’ve struggled mightily with how to effectively communicate the idea that for cryonicists, a singularity of truly incredible magnitude has arrived and that it is one which, in theory, should be available for use by us now. I’m reasonably sure I’ll fail in that task and that no matter how I might have framed the argument, or presented the evidence, the outcome will remain the same. And therein probably lies yet another powerful lesson about why Singularities, wherein everything is transformed in the blink of an eye, never really happen.

How ‘Fast’ are Most Medical Singularities?

Medicine, ironically  much more so than entertainment or warfare, is bound up with the sensitive issues of ethics and morality, which have historically complicated and often slowed the propagation of paradigm changing, or so called “singularity events” within its confines.  Vaccination, contraception, anesthesia, organ transplantation, mechanical life support, resuscitation medicine, in vitro fertilization and embryo and gamete cryopreservation have all been slowed or blocked altogether as a result of religious or ethical concerns. (1,2,3) Indeed, surf the net or turn on TV today and you will see hordes of angry people decrying vaccination, contraception, and arguing furiously over life support. Support for vaccination, ~212 years after Jenner, is even eroding in the nation that spawned it!

The idea that wound infections – sepsis – were caused by a contact-transmissible agent was definitely proved by 1848, in the form of the exhaustive statistical work documenting the effectiveness of antisepsis conducted by Semmelweis. By 1860, the theoretical grounding for the basis of that transmissible agent, germ theory, was in place. Scattered throughout Europe there were a few men who understood the new paradigm and could no doubt foresee many of its practical implications in medicine. These men must have been as frustrated as cryonicists in the middle of this last( 20th) century – men like Pasteur and Koch. If ever there was a singularity in medicine, this was it. And yet, what happened?

Figure 4: President (then General) Robert E. Lee of the Confederate States of America receiving his critical Magic Lantern briefing on the revolutionary, but heretofore unappreciated work of the Hungarian physician Dr. Ignaz Phillip Semmelweis, concerning the importance of antisepsis for the control of infections in battlefield and surgical wounds. The information proved of a vital strategic advantage in helping the Confederacy to successfully prosecute the war against Union forces. Lee is seen here in the sitting room of his home in Arlington, Virginia in this classic painting by John Elder.

Perhaps it might be more instructive if we ask ourselves what should have happened according to the Singulatarian, or even according to the “popular” model of how  powerful, beneficial ideas with virtually no downsides spread through the culture. For instance, one of the most popular “what if” questions in the realm of alternate history is, what if this or that had been different that would have altered the outcome of the United States Civil War?(4) Military historians all have their favorite “what ifs” in this regard, but mine, well mine wouldn’t be military at all, but would come down to a long, drawn out Magic Lantern (PowerPoint) presentation given to a very receptive General Robert E. Lee, on the eve of the Secession. The subject of that presentation would be the revolutionary findings of two maverick Europeans; Dr. Ignaz Philipp Semmelweis, and  Dr. Louis Pasteur, as they apply to battlefield medicine and the recovery and survival of injured troops in the conflict to come.  The Confederacy lost the war for many reasons, but in the end it came down to a lack of manpower and the disproportionately draining and depressing effect that combat related sepsis had on the South. [At least, that's my story and I'm sticking to it ;-).]

Lee would listen, his military surgeons would be briefed on the Confederacy’s “secret weapon” and the tide of history would be turned. Wild and playful imaginings? Yes, but they constitute a considerably more reasonable scenario for the rapid adoption of asepsis in the US (or even half of it!) than just about any other you are likely to come up with, because the reality of what happened is almost incomprehensibly tragic.

Figure 5: In his magnificent painting entitled The Gross Clinic, Thomas Eakins graphically captures the state of surgery in the US during the decades following the US Civil War. These grotesquely unsanitary conditions had by this time to a large extent become a thing of the past in surgical theaters through much of Europe.

Figure 6: Even 14 years later, when Eakins revisits the them of the operating theater in his painting The Agnew Clinic, full adoption of asespsis and antisepsis had not occurred in the US.

Semmelweis’ work had already been published and disseminated around Europe by 1848, and by 1861, the year the American Civil War was opening, Lister was reprising Semmelweis’ discovery of antisepsis in Scotland, not with chlorine, but with carbolic acid. The sad reality was that the Americans (North and South) were so pigheaded regarding germ theory and the value of asepsis and antisepsis to medicine, that it would not be until well into the 19th century before that particular singularity fully took hold of the United States.(5)

Indeed, Lister made an “evangelical” tour of US medical schools in 1876 to little avail.(6)  Whilst the Listerian revolution was well underway in Europe by then, the situation in the US was to remain, as it was so vividly portrayed by Thomas Eakins in his magnificent oil, The Gross Clinic, which was painted the year before Lister’s missionary visit to the germ loving heathens across the pond. Fourteen years later, when Eakins painted The Agnew Clinic, we can see the beginnings of asepsis just starting to take root in the form of basic cleanliness being imposed in theatre. Clearly, antisepsis/asepsis are an example of a technological singularity in medicine, albeit one that took onto a century to fully unfold!

The Problem of Bite Back

But beyond these arguably irrational roadblocks slowing the progress of technological singularities in medicine, there are two others: the very real problems of their rational management on both the macro and the individual (patient) scale.

Figure 5: Edward Tenner’s excellent book, Why Things Bite Back explores many examples and a number of reasons why technological advances often fail to reach their expected potential, and in fact, not infrequently turn out to be self limiting, or even self defeating.

Some of the technological singularities just listed, vaccination, for instance, can have very serious practical, economic and societal consequences. Rapid and widespread introduction of vaccination into equatorial Africa by Christian missionaries, absent the concurrent introduction of agricultural and other infrastructure, resulted in a population explosion and mass famine which has not abated to this day. Oral contraception has resulted in huge demographic and social changes occurring within a single human generation; a heretofore unprecedented event in the history of our species.

While medical advances are usually perceived as an unalloyed good for the patients who will benefit from them, this is rarely, if ever the case. The discovery of x-rays opened the interior of the human body to non-invasive examination, but it also exposed the patients so viewed to initially unsuspected exposure to damaging radiation – a problem that persists in radiologic medicine through the present. Beyond the problem of unforeseen or unknown dangers, there is also the problem of technological bite back, or what Edward Tenner has called the “revenge of unintended consequences.”(7) This is a major adverse effect of technological singularities, and one which often robs them of much of their anticipated bounty – not just for societies, but for individuals as well.

As I’ve just pointed out,  new medical technologies are sharply constrained in their utility at their start due to our inexperience with their bite back potential, and with the possibility of unknown  direct adverse affects of the technology  itself. However, every great once in awhile there are peculiar exceptions, and it just so happens that cryonicists are ideally positioned to enjoy just such an exception, starting now.

Your Picture Won’t Be Hanging Here?


Reception area of the Alcor Life Extension Foundation in Riverside, CA in April of 1987. The photos above the refreshments cart were of some of the patients in Alcor’s care at that time.

Sometimes we get defeated by technology, sometimes by cluelessness and sometimes by a most unexpected intersection of the two.

In 1981 I conceived of the idea of hanging the picture of each patient cryopreserved at Alcor on the wall of the facility. I intended the practice to start, not in the place where it might seem obvious for it to; in the patient care bay (PCB) as a memorialization of the patient for his family and friends, but rather, in the reception area and offices, where the organization’s staff dwelt on a daily basis. It was my intention that as the patients accumulated in the PCB, the photos would begin accumulating in the offices, laboratories, corridors and workspace of the Alcor staff.  The intention was to provide a not so subtle reminder that there were people in those big stainless steel tanks, people who were desperate to get out of there.

My intention was that, over time, there would an inverse and very adverse relationship between “success” in terms of patient population growth and “failure” in terms of growth in the number of pictures on the wall. In time, I envisioned (with some glee) the framed photos multiplying like locusts, becoming ever more oppressive and occupying ever more wall space.  I foresaw that they would likely encroach into the PCB. I also thought it likely they would be downsized. But mostly, I hoped they would serve their primary function, which was that each one was to serve as a reminder to those working at Alcor: “Hey, I’m still waiting, get me out of here! I want to get back to living, just like you are, too!”

This was not an idea which I kept secret. It was frequently discussed with other Directors, with staff, even with the officers and directors of other cryonics organizations. In fact, I now believe it is a practice which has become universal at cryonics organizations around the world. Or should I say, had become universal.

Alas, I hadn’t counted on technological advance. Technological advance is almost always a “two sided blade” and is this case, the blade cut in a way I hadn’t at all foreseen. The digital photo frame makes it possible to store essentially an “infinity” of images, and display them all in the physical space occupied by just one, over short sequences of time. In so doing, it removes the clutter, and thus the annoyance of hundreds or even thousands of actual framed, photographic images. One problem solved.

And another created. The purpose of institutions is to attempt to overcome the most damaging consequences of human mortality to civilizations: the destruction of knowledge, wisdom and the values they enable. In short, the loss of memory and accumulated experience that comes with the death of individuals.

Enter the halls of any civilization’s venerable institutions and you will see the images of the individuals they treasure on their walls and of those individuals’ ideas encoded in the books lining their shelves and engraved in the form of quotes and aphorisms on their walls. Stroll their great cities, or the corridors of their museums and you will see statues and likeness of the persons they treasure and admire cast in bronze and carved in stone; all these things are feeble attempts at conserving the ideas and values of the individuals who created the intellectual capital that sustains their civilizations. It is not just that they owe these men personally (they do) it is that these civilizations survive by remembering and living by the ideas that these men created.

Unfortunately, it turns out that ideas, standing alone and absent the context of memory, are weak things. It is one thing to know that fire burns, and another thing altogether to know that fire burns having been burnt by it. It is the power of knowledge in the context of experience that is wisdom, and it is wisdom that is destroyed by death. Knowledge contained in books, or nowadays in digital form, is but a shadow compared to that contained in the mind of a man who knows the real truth of a thing in the context of personal, hard won experience. Feeling, guided by reason over time, is the most powerful tool in the universe; and death is its ultimate enemy.

The human institution (first as oral tradition) followed by the written word, were man’s initial tools against death. Poor instruments that they were, they were used to fight valiantly in an attempt to conserve the memory of what was – a story of people, places and events over time. They were, to a remarkable degree, successful. The Royal Society is almost unbelievable in this regard, with every scrap of correspondence and every minor triumph and squabble being recorded and preserved. So are many neighborhood British garden societies – many going back hundreds of years. This will be true of every successful human institution from enduring religious institutions such as St. Catherine’s monastery in the Sinai, to the fraternal organizations such as the Masons in the US.

Robert Ettinger (left).

With the advent of scientific medicine and Ettinger’s book in 1964, it has become scientifically credible for human beings to reach for personal biological immortality and thus, for the first time, for a credible and a definitive “end to death.” Because what death really is, is the destruction of human knowledge and wisdom, and that is always and necessarily rooted in the destruction of individual humans. Wisdom, in particular, is uniquely a property of individual persons, and so is creativity. Neither of these fantastical properties which create and drive civilization can be distilled into books, carved into stone, or molded into bronze or plastic.

To achieve immortality for individuals it will be necessary to utilize the structure of institutions. It should be abundantly evident that such institutions will necessarily have to be the most stable and durable of those which human beings have so far managed to engineer. As such, they will have to most emulate that property which human institutions were created for in the first place: the conservation of memory of persons, places and events in order to conserve values over time. This why institutions incessantly speak of things like “grand old traditions” and “institutional memory.”  Admittedly, it is a hard thing to do. And it is a perilous thing to do, because it relies upon successful prognostication of the future; that the ideas and values selected for conservation and propagation over the ages are the ones essential for success; and that the ones not essential, do not discredit those that are.

Inherent in cryonics is a terrible arrogance and optimism which attracts a kind of people who seem to possess an inborn contempt for, or incomprehension of the value of the past. This is evident in their own disregard for it. There is a shocking lack of historical conservation at both CI and Alcor. In fact, it is so shocking and all pervasive that I know that my words here will have virtually no impact on almost all who read them, because no one,[1] at either place has any idea of what I’m talking about. It is, literally, the equivalent of talking to people who have never seen books, about how shocking it is that they don’t have libraries.

Organizations that are clueless about their own (recent) historical past should, not surprisingly, also be clueless about the deeper reasons for things like pictures of patients hanging on the walls. A few years ago, I was talking with one of the (many) former Presidents of Alcor who had a question for me about  something in a member’s paperwork. This President wanted to know what “BACS” was? Now, I am old. In fact, I’m a little older than cryonics (by about 9 years). But that still only makes me 56, not 156.  I felt a little like I do when I see anyone in the US being stopped on the street and asked questions like, “Who is the Secretary of State?” or “Who was Abraham Lincoln?” and the response is an utterly clueless answer.

If you’re an average reader here, and you don’t have a clue, that’s OK, because there really is no cryonics community to get acculturated in. The answer is that the Bay Area Cryonics Society (BACS, they changed their named to the American Cryonics Society, ACS, in 1985) was the dominant cryonics organization in the world from ~1974-1984! That’s a third of all of cryonics history and it’s not that long ago.  To not know that and to be running the world’s largest cryonics organization seemed wrong to me. Not because it was wrong per se, but because it was inevitably a marker for what had to be a veritable iceberg of other missing information that was of far greater import. And even that isn’t necessarily a fatal flaw. Realizing a deficiency of knowledge or character or resources, even a spectacular one, and working hard to remedy it is the oldest heroes’ tale in the world.

Of course,  it isn’t really practical to keep putting up pictures of Alcor’s patients on its walls. At some point, I’d have expected that they would have started to spill out, rather indecently, onto the grounds. And perhaps, if the problem persisted far enough into the future, they might start turning up, well, who knows where? And continue to do so until the problem was solved.

The problem to be solved being not the clutter, nor the barrier to tasteful decorating, nor to efficient housekeeping, but rather, the problem of how to make their number start decreasing, rather than increasing. That is, decreasing by some expedient other than by gathering them up into a digital dustbin where they are granted increasingly smaller and smaller and smaller access to the living human eye, as time goes by.

How terribly (horribly) convenient.


After writing this piece it occurred to me that many might dismiss it as a case of “sour grapes;” of an “old man” failing to keep pace with the times. I don’t believe this is so and I think a good analogy is the AIDS Quilt.  Imagine if the AIDS Quilt had, because of its bulk, logistical inconvenience, and in your face anguish effect, had been replaced with a single (or several) flat screen “quilt display” monitors?

The effect would hardly have been the same. At issue here is not the technology, per se. I can imagine a number of ways to use digital technology far more pervasively, far more more subversively, and potentially even more durably than analog photographs, or stitched pieces of fabric. I’m not an analog Luddite. Indeed, I’m using digital technology in just such a”creative-subversive” way right now.

The point is that it must be used in such a manner – transformatively, transcendently and creatively – not as a band-aid convenience to assist with interior decorating to “reduce clutter” or “ease housekeeping.”

That is the clueless failure of vision, understanding and institutional memory I’m addressing here.

Bon Voyage, Fred Chamberlain

By Mike Darwin

Me and Mei Lei, settling down after dinner and a peek at the heart of the time machine, which was then kept in a shed in back of the the Chamberlains’ home in La Crescenta, in 1973.

I was an 18 year old kid feeding quarters into a payphone in front of a Piggly Wiggly grocery store at 9 o’clock on a summer night in 1973, in Augusta, Georgia. On the other end of the line was a middle aged aeronautical engineer in La Crescenta, California, not far from the Jet Propulsion Laboratory, feeding me dreams. He wasn’t telling me about the spaceship he was working on to explore the outer planets, instead, we were talking about the time machine he was building to take us to the future. You see, I was helping him with the design – my part was the bubble trap, where pressure and temperature would be measured.

The “front-end” of the “time machine” in 1973, before the bubble trap was designed, fabricated and installed.

The engineer’s name was Fred Chamberlain, and we had met the year before at his home where he, his wife Linda and I had had dinner and had looked over the various parts of the time machine project. It was then that I noticed that the device was missing a critical component – a bubble trap – a device to prevent dangerous air bubbles from entering the circulatory system of the time traveler. Fred immediately saw the importance of the oversight and I set about designing a bubble trap that would fit into the device as he had already configured it.

The glass bubble trap for the “front-end” part of  the “time machine” in use to perfuse Fred’s father in 1976.

We had been in correspondence for several years before we  met. Though I was just a boy, we shared a dream to voyage into space and conquer the stars. To do that, both of us understood we would have to become time travelers, because we were trapped in a time and place that was wholly unsuited to our ambitions and aims. We had been born too soon. We were doomed to grow old and die before our species mastered the technology to venture forth from the world of our birth and set sail into the cosmos. The only way we could see out of this tragedy, Fred, Linda and me, was to become time travelers, in fact to become a very special sort of time traveler – medical time travelers.

Linda Chamberlain in 1974.

What kid, then or now, wouldn’t kill to have a life like that? Isn’t that the stuff that dreams are made of and the juvenile SF novels are plotted around? Nobody has a life like that and everyone knows that a story like that couldn’t possibly be true. Have Spacesuit Will Travel? No doubt. Have time machine? Well, then then you’ll really go places!

The working heart of the time machine!

And yet, every word I’ve written there is true, and I’ve got the pictures to prove it; and you’ve just seen them.

Fred Chamberlain was a NASA-JPL electrical engineer working on the Mariner-Jupiter-Saturn mission in 1973, and we had that conversation and many like it. And we planned the mission Fred began yesterday and many more like it before, and to follow. The time machine we were working on was actually for a “fourth” of us, not mentioned in my story, Fred’s father, Fred, Jr., and it was indeed used to launch him on his journey on 16 July of 1976. And yes, my bubble trap was an integral and a successful component of that mission.

Fred, Jr., and Fred, III, father and son, now time travelers awaiting rescue.

Frederick Rockwell Chamberlain, III was and is of absolutely critical importance to cryonics. While most people with more than a passing acquaintance with cryonics will associate his importance with the founding of Alcor, that is in reality only a surrogate marker for his deeper importance. Fred came on the scene in cryonics in what was unarguably its darkest hour. It had degenerated into little more than a fraudulent cult in California and, everywhere in the US, it had lost all vestiges of technical and scientific rigor.

When Fred discovered this in his role as Vice President of the Cryonics Society of California (CSC) he not only left CSC and founded Alcor, he and Linda Chamberlain established, for the first time anywhere, the practice of scientific, evidence-based cryonics; cryonics based on the scientific method, on documentation of procedures, policies, cryopreservation protocols and rigorous patient case reports. He and Linda mandated not only scientific and technical accountability, but administrative, financial and legal accountability as well.

Standardized procedures, protocols, equipment and meticulous documentation were critical elements Fred and Linda Chamberlain brought to cryonics.

In doing these things, Fred and Linda attracted and mentored others. Fred’s personality and his military background brokered no compromise and his mentoring profoundly shaped me and a few others, molding us into the irascible and generally disagreeable inhuman beings we are today. At one time Fred was responsible for replenishing the tritium supply of all of the hydrogen warheads in the US nuclear arsenal. Men given that responsibility do not suffer fools gladly.

Personally, Fred taught me a great deal about engineering; not about the mathematics of it, but about engineering at the systems level, about how to look at a complex problem and tease it apart without being overwhelmed by it. He had a fantastic ability to see and solve problems at a meta-level, and he was able to communicate that to others.

Fred Chamberlain helped to build three incredible machines all of which had their origin at roughly the same place and at roughly the same time; in the foothills of the Santa Monica mountains near Pasadena, California in the early 1970s. Two of these are the Voyager spacecraft, now on their way to the stars moving  through the heliopause at 16.6 km/s  and 19.4 km/s, even as I write this. The other, the medical time machine begun when I was a boy, even before that pay phone call in Georgia, is, for the moment, located in Scottsdale, Arizona and it is moving relentlessly forward with its precious cargo of time-stopped souls one slow day at a time. Godspeed to all of you!



 You can believe me when I say that I do have some idea of your loss. Only some, I’m sure. It has been a hell of a last few weeks for me, but nothing to what you’re going through now.

 Man, oh man! I miss him already, and I haven’t laid eyes on him in years.

 I remember all those years ago in La Crescenta, we were so young, and yet we were planning for this very goddamn eventuality. We were actually planning for it, thinking about it, talking about it, working towards it. We knew it would come, and in a weird sort of way, we hoped it would come, because the alternative would be that if it didn’t come for us at all, we would be one of the truly unlucky ones that fell through the cracks, like Marce did. Still, we have his loss to bear for now, and for some unknown seasons of tomorrows yet to come.

But remember Linda, it was just yesterday that we planned for this day now so soon arrived – a plan that has been, as we so rightly foresaw, flawlessly executed. Now, let us be patient just a “little” while longer, and work again, just a “little” bit harder, so that we can awaken tomorrow, and find that that other day that we talked about, dreamed about, planned for and worked towards has also arrived, in which we find ourselves together again – not in “paradise,” but in this world, planning for, thinking about, talking about and working towards those other dreams that we had to put on hold, simply in order to survive.

Let us look forward to those goals and dreams and many, many more still undreamt and unimagined, to which we shall again apply ourselves when the tear-blindness of our grief subsides.

Fred Chamberlain III: First Life Cycle: 1935-2012

by Linda Chamberlain


Fred Chamberlain III recently had his brain placed into cryostasis at the Alcor Life Extension Foundation in Scottsdale. His physical presence will be missed by many friends, biological family and chosen family until technology allows a future instantiation to be with us once again.

Among his many talents, Fred wrote inspiring poetry and loved to play the guitar and keyboard. He was one of the most intellectually creative and energetic people I’ve had the privilege to know. He just recently published BioQuagmire, which in my opinion is the best transhuman, life extension novel ever written. Fred (together with me and other authors) published a volume of life extension and transhumanist short stories in the 1980s called Life Quest.

The picture above shows Fred when he was in his twenties working in bomb disposal as a Navy diver. He was interested in ethics and was a strong supporter of Ayn Rand’s ideology. Fred became actively involved in cryonics in 1969 in order to get his father, Fred Chamberlain Jr., suspended (Alcor News, August 1976). Fred and I met and became Forever Buddies in 1970 while working on the committee to organize the second national cryonics conference, held in Los Angeles, CA.

Here we see Fred in his thirties, sitting on the rim of the Grand Canyon. He was an engineer at the Jet Propulsion Laboratory (JPL) in Pasadena, Southern California, where he worked on the Voyager missions to Jupiter and other fascinating projects.




That’s when I first met and fell in love with him. One of our great intellectual and emotional bonds was our interest in technological means of extending life. Fred and I incorporated the Alcor Life Extension Foundation in 1972; the minutes of those early Alcor meetings can be viewed by  those who might be interested. Many details from those early years are available on Wikipedia.



The photo to the right shows Fred in his 60’s when he and I were again active in Alcor between 1997 and 2001.




The picture on the left shows us in 2002 when we renewed our wedding vows on a beach in Cozumel with a traditional Mayan wedding with both of us wearing traditional Mayan wedding dress.

Inspired by the Mindfile tools and programs being developed by Terasem (including but not limited to and, and seeing Mindfiles as an absolutely essential part of any personal life extension plan, we moved to Melbourne, Florida in 2010 to contribute as much as possible to the Terasem Movement while we remain in biological bodies, and then continue doing so when emulated as cyberbeings. We made a presentation about Cybertwins at Terasem’s 5th Annual Colloquium on the Law of Futuristic Persons in Second Life (on Terasem Island), on December 10th, 2009.

Fred recently had his brain placed into cryostasis at the Alcor Life Extension Foundation in Scottsdale, to preserve his Connectome as additional Mindfile information. Though I will have to carry on alone for both of us for a short while before we see each other in cyberspace, Fred is still part of all of us in the Terasem Collective Consciousness and we will continue to enjoy his warm creativity again soon as well as through his poetry and many writings.

As they say on the Star Pebble, See you in the next cycle.

With all my love,

Linda Chamberlain

Many years ago in The Immortalist (now Long Life), there was a column authored by one Robert Brakeman.  If you’re a fan of Seinfeld (and I’m not) then Brakeman was a genius, because he did in print what Seinfeld did on TV; wrote a column about nothing that a lot of people found entertaining.

Brakeman’s column was not controversial, or technical, or sentimental, or political, or artistic; it was just a well written column about, well, about nothing. Except that every year or two he would casually discuss how he and Bruce Springsteen had decided that cryonics was a really good idea. Or it might be some other, equally legendary celebrity. The first couple of times this happened I didn’t pay it much mind. Cryonics is a quirky business, after all. However, after the third or fourth time, I wrote a letter to the editor of The Immortalist, Mae Ettinger (then Mae Junod) and I asked her if anyone there had ever met, or even spoken with Robert Brakemen, or otherwise vetted him?

Mae Ettinger did not normally refer to me by name, preferring instead to use the moniker “Evil Genius,” when not calling me the “Great Satan.” The subsequent correspondence between us was neither cordial nor long.  Brakemen continued to write in The Immortalist until, eventually, I, or someone else (I really don’t remember the particulars) called Mae out in public over who Brakeman was and whether it was really true  that all these celebrities were, in fact, true-believing cryonicists, as claimed by Brakemen in the pages of The Immortalist. After that,  there were no more columns by Robert Brakeman.  I never did find out who he was, but I would not be surprised to find out today if people were accusing me of being him. If so, I’ll happily take the credit: that guy was one hell of a writer.

In the history of cryonics there have been many pseudononymous individuals and nom de plumes. This is to be expected in any area of endeavor where there is controversy and risk to one’s career and reputation. However, in the early days of cryonics and up until the advent of the Internet, the presence of anonymous actors was extraordinarily rare. To be sure, people changed their names; I’m one of them. But that is very different than being an anonymous actor (IA). There is nothing sneaky about being Mike Darwin or Max More or Bette Davis, for that matter. People get to pick their own names as long as they stay people; discrete, identifiable beings who are responsible and accountable for their actions. People who don’t like that are entitled to their opinion, but the act of adopting another name isn’t illegal, so long as you don’t adopt another identity in the bargain.

Sometimes, rarely, the use of another name to create an AA is, arguably, justifiable. The Lone Ranger, “V,” the Three Musketeers, the list of anonymous heroes created in response to tyranny is endless. In cryonics, it could be argued that Corey Noble, PhD., once served that role in response to the tyrannical actions of the Society of Cryobiology. But the need for anonymous actors in daily life is pretty rare. Today, as far as cryonics is concerned herein the US, it is virtually over.

And yet, the reverse has happened. Whereas until the advent of the Internet in the 1980s there were almost no  AAs in cryonics, now, that is almost all there are! What gives? The list is endless and I can’t begin to catalog them all: unperson, Finance Department, Desert Rat, and the more distant past, Clarissa Wells…  Most of these names are  “handles” and this practice has its origin in a related technology: radio.  An important difference is that radio, unlike the Internet, operated in the realm of limited bandwidth. The electromagnetic spectrum is inherently limited by physical law. That meant regulation and licensing. And that meant that “handles” were ultimately, at least in theory, traceable back to real, responsible people. With the Internet this is not the case at all.

Of the list of anonymous actors I’ve just given, I’ve been accused of being Clarissa Wells, Finance Department (FD) and unperson. I eventually found out who Clarissa Wells was (and it wasn’t me) and I have had extensive correspondence with FD (I’m not that crazy), so I suppose that still leaves unperson as a possibility. But the fact of the matter is, other than as a one-time prank, I’ve never used a pseudonymous person or an anonymous actor, on or off the Internet.  I find it deeply offensive: so offensive I’ve even turned down significant sums of money to do it for hire.

Over the past few days I’ve been thinking big thoughts about the ‘how and why’ of the recent emergence of this phenomenon. Finally, today, I realized that there is no big philosophical reason for it. People do it for a single, simple reason: BECAUSE THEY CAN. It is a whole hell of a lot easier to be able to say and do whatever you want and not be accountable for it. It turns out that even if you are bright, talented, and have a great deal to offer and be rewarded for, it still easier and more rewarding to act outside your primary sphere of professional and personal action in an anonymous way than it is to jump through the hoops all over again and gain recognition in a small pond the hard way, just as you did in the big one. And to that, I have the following response: fuck you and the fish you swam in on.

So, from now on, the following rules pertain here in the Chronosphere pond. No handles are allowed. Only  real people can post or comment here. Maybe Eugen Leitl can help me figure out how to implement that. I’m not looking for something elaborate – just something as “real” as a letter used to be.  No more wackywackys from the ether.  If that’s the end of Chronosphere, or comments on Chronophere, so be it. I respect peoples’ rights to geographical privacy. I’m not trying (no do I want) to know where any person is at any point in time or space. I just want to know I am dealing with a real, accountable, person, not a cyberphantom.

The Logical and Intellectual Bankruptcy of Christianity

by Mike Darwin

I can remember, with unfortunate precision, when I ceased to believe in God. Please note the emphasis on the “I” and the capitalization of God.

I was seven years old and being prepared for my First Communion in the Roman Catholic Church. I do not know what this entails today, but at that time, being enrolled in a Parochial school before the advent of Vatican II, it was an elaborate, 9-month long process of indoctrination and ritual. The church I attended was dark, Gothic, aromatic and overawing.  The nun who instructed me and my class was kind and compassionate, but also knowledgeable, stern in her faith and firm in her convictions.

Sister Mary Ephraim (Right)

Amidst the endless rote memorization of the articles of the faith of the church and the various moral absolutes and injunctions, were told often, and in hushed tones, about the sacred transformation that was about to occur in us. The Holy Ghost was about to enter our bodies and sanctify and purify us, and we when the priest put the Host upon our tongues, the Body of Christ would enter into us and we would be filled with the Spirit of the Lord. This was to be a a transformative moment. In retrospect, it seems very strange that out of that first grade class of 30 or so children, not one ever asked a question along the lines of, “What does it feel like to have the Holy Ghost enter your body?” or “What does it feel like to have Jesus inside you?”

To my knowledge, no one asked those questions there in class, or at home of their parents, or to each other during recess, or after school, or at any other time. Remarkable!

And so the time came and I had my First Communion and the celebratory breakfast at a local restaurant afterwards. I’m smiling in the photos taken at that event and seemingly enjoying my gifts. But inside, I am already desperately unhappy, because whatever  magical feeling was supposed to have happened; it didn’t happen to me. Again, strangely, I didn’t discuss this non-event, and neither did anyone else, if indeed, it was a non-event for them.  And so, from that day forth I knew that for me, at least, there was no god. The capital came off the g and, gradually, as time wore on and my intellectual horizons began to grow, I realized that probably most of the other kids in my class had had a pretty similar experience to mine. There had been no hallelujah moment, no inward whoosh of the Holy Ghost, and urgent need for temporary immunity with a sanctifying jolt from Jesus that had to be renewed once a week with Holy Communion.

Grade School Graduating Cohorts: 1969. How many felt the rapture?

Their belief had become not a direct belief in that tangible supernatural experience, but rather a belief in the belief of the goodness and the rightness and the necessity of that experience, and as a side effect, of all the dogma, doctrine, ritual and machinery of the church that was tied to it. Of course, I did not understand why they believed that and  why they needed to believe it; so I kept my mouth shut and went along with it until cryonics entered my life.

Cryonics changed everything, because it was the key to understanding the fundamental reason for the need to believe in religion and that was in turn the need to deal with the central and most pressing problem of human existence (which is not, as most philosophers would have you believe “man’s purpose in the universe,” but rather, the problem of DEATH. A writer who particularly influenced me (via cryonics) was Alan Harrington. with his radical manifesto The Immortalist. Once I read The Immortalist the key turned in the lock and the door opened. Religion was a coping mechanism it was a sanity mountainous device that had no more basis in reality than Santa Claus or the Easter Bunny.  From Harrington I learned of Miguel d’Unnamuno and then, in my Sophomore year of High School I read Ernest Becker’s The Denial of Death which frames the whole proposition from a more rigorous cognitive perspective.

In more recent years, I’ve become increasingly convinced that religion, religious thought, religious beliefs and mystical experiences are likely rooted in our evolutionary biology and that, as opposed to being merely a social tool for coping with the terrible reality of death, religion may have an evolutionary-biological basis, as well.

The implications of that, if true, are powerful and staggering, because it means that as we outgrow the need for such ancient and irrational coping mechanisms, it will be difficult to set them aside – more difficult than we may have previously imagined. As a consequence, we will need all the tools of logic and reason at our disposal to demolish the infrastructure of religious thought.

Growing up, as I did, in a religious environment, and being both an atheist and a cryonicist, I was confronted with many religion-based arguments against cryonics and immortalism. This was also a time of stunning advances in biomedicine and cryonics was all about the promise of more to come. At that time, and even more so now, the party line within the cryonics community was one of strict appeasement with respect to any conflict with religion. “Don’t antagonize them. We need the members. Keep your mouth shut.” Those were the bylines. Mostly, I held my tongue. But I from time to time I would mumble, under my breath, the thought I often had after the shame  of not feeling the rapture of the Holy Ghost (nee’ Holy Spirit) pouring into me or Jesus not suffusing my being after Holy Communion: Well, you know, the only thing that would have lent real credibility to Christianity is if, when Jesus, God’s beloved only son, exsanguinating on a rough hewn cross of wood, cried out, “E’-Li, E’-Li la’-ma sa-bach’-tha- ni?[1]” there was absolutely no answer, and that was really the end of it. No resurrection 3-days later. No atonement for mankind’s sins. Just oblivion. No backroom deals, no escape clause, no abracadabra, no miracle.

I mean, honestly, how scary is obliteration if it lasts only as long as a 3-day bender, or an especially bad bank holiday weekend? How big a deal is death, if it really isn’t forever? I was coming of age in a time when people were recovering from comas that lasted for weeks for or months – and in rare cases even for years! Three days? Give me a break! On a purely logical basis, Christianity doesn’t make any sense. As we cryonicists are quick to point out, there is a serious logical fallacy if the definition of death is the irreversible loss of life, and yet dead people can supposedly come back to life, get married have children, grow old and die again, ‘cmon!. Where’s the sting in that? So Jesus died?

OK, so lots of people “die” nowadays. They suffer and “die.” They exsanguinate slowly, they suffer injuries so terrible that they make Jesus’ brief tenure on the cross and his march down the Via Dolorosa look like happy hour on Folsom Street in San Francisco. And what’s more, they live – and they live long, satisfying and productive lives, including people like the one in the photo above. And they do so, not because of anantiquated coping mechanism for death and mayhem, but because of rational, scientific inquiry and its application to medicine by courageous and dedicated men who value life and want to preserve and extend it.

One good thing I can say about Roman Catholicism is that a central tenet of the faith is that it must be accepted willingly – not through coercion.  As a consequence, the adherent is asked at numerous junctures if he is he is indeed a believer. Me being me, I said no, early and often. My parents’ response to this was to force me to observe the rituals of the church. I was made to attend Mass. However, to their considerable credit, the priests and nuns would and  did not cooperate in any way with my parents’ attempts to force further participation. So, while my parents sat and stood and keeled and spoke as the ritual dictated, I merely sat. And so it went until this ordeal became too embarrassing for them.

My parents never interfered with my intellectual autonomy. They never even attempted to interfere with my signing up for cryonics at the age of 15, with embrace of Darwinian evolution, or with any other of my beliefs or ideas. Somehow, they knew and respected that cryonics, in particular, was absolutely critical to my person-hood and to my dignity – indeed that it was central to my integrity as a human being. I could then only imagine what it must have cost them to do that.

When I saw that my mother was developing Alzheimer’s Disease (AD), a number of doable scenarios crossed my mind that would have allowed me to cryopreserve her, or to otherwise render her brain into a fixed, unchanging state. I have done this before in very different situations for very different reasons. How is not material to what I have to say here. The fact is, I would have done almost anything to have saved my mother. I would have stolen or killed  to have saved my mother.

The one thing I would not have done is to have defiled her autonomy. And therein lies a terrible irony, because, at the very cost of her own life, the values she, and her logically bankrupt religion taught me, stayed my hands.

Will she and all the other dead be recoverable some day in some way in an infinite universe or multiverse? Perhaps. That’s what the theoretical physicists tell us this week. Maybe in 13 billion years we will all be united end of the space-time continuum.  Does 13 billion years matter? Hell yes! Three days? No so much. We aren’t gods and the fact is, we are so far from it we can’t even approach that throne, look upon it, or begin to understand it. So for all practical purposes, 13 billion years is forever and for now, dead is dead. We need to keep that in mind as we reason our way forward day by day and make the decisions that shape our lives and the lives of those we love.

ii Mirror mirror hanging on the wall, CryoX: Birth of NeoInsurgent Cryonicst

By CryoX

{This is a work of fiction  {or is it?}

Mirror mirror hanging on the wall
You don’t have to tell me who’s the biggest fool of all
Mirror mirror I wish you could lie to me
And bring my baby back, bring my baby back to me – m2m

My frequent flier card isn’t a card at all, it’s Parthenocissus tricuspidata (some would argue it’ the Roman numeral IV, instead). Whatever. For me it’s the magic weed that evaporates the financial distance between the coasts three or four time a year. Most of my frat buddies have their business junkets, we academics have our conferences. Alcor and Mike Darwin. Both on the West Coast, as  was my upcoming conference. Doable.

I hadn’t seen Max More since my undergraduate days, which I realized were rapidly becoming, no pun intended, a chillingly long time ago. My girlfriend (at the time) and I had attended some cryo/extro/CR get-together’s, and I met Max and his wife Natasha several times.  Max was this earnest, muscular, ginger, intellectual type who tried just a little too hard, was just a little too rehearsed and was more than a little too rigid. His wife Natasha? In some slightly different AU, Kurzweil has his Ramona. To me there is something artificial, slightly off and s-t-r-e-t-c-h-e-d t-a-u-t about her.  The only time I met Max without her around, I noticed a big difference in him; he was visibly insecure.

Now, Max More is President of Alcor.

I should have called to be sure Max was going to be there instead of just booking for the tour. Stupid. My flight was delayed out of LAX, and with the crazy delay from the limo, I barely made it from Sky Harbor to the Alcor building in time to meet the rest of the group. Unbelievably, the traffic in Phoenix is worse than it is in L.A.

The Alcor building is drab and unimpressive which, because of the idiodyssey of my limo driver, I really don’t understand. There are two Acoma Drives in Scottsdale and the moron (or his company) driving me from the airport had no GPS. We spent half an hour cruising around the Scottsdale Air Park before I finally became desperate enough to shove my Droid in his face and demand he call someone for instructions (shame on me for not having my GPS enabled for travel). The Air Park has lots of architecturally attractive buildings – some quite stylish if you like that Frank Lloyd Desert Look. The Alcor building is Brutalist Bad; plain-ugly-anywhere.

As soon as we were admitted to the lobby/reception area, a bomb went off in my head: Natasha! I don’t know if she had anything to do with it, but that was my reaction.  That kind of space is, by definition, supposed to welcome and draw you in. Instead, there is this big, cold, crystalline blob in the form of an “Infinity Mirror” almost immediately inside the door on the wall to your right, as you walk in.

There are all kinds of problems with this. First, it causes a distraction. The visitors aren’t interacting or socializing with each other, or the Alcor staffer (who should be a scantily clad voluptuous blonde). Instead, they are looking at the “pretty” on the wall, and some of them are even ape-touching it. One Merkeley woman in the group poked me in the ribs and said in an excited whisper, “Oh look into it, look into it.” That was my undoing. Fun-house mirrors, looking down tall glass buildings, certain angles at the Las Vegas  strip: all provoke intense, uncontrollable vertigo and nausea. Instantly, I was an undergrad in a dorm room staring up at an empty case of Dos Equis from the floor.  In one direction was the door to the outside, which the lady who had let us in had locked with a key. In the other direction was a mass of sharp angled stainless steel and glass furniture which I could see myself impaled upon and dying in a pool of my own blood and vomit.  I was paralyzed in front of the magic mirror. All I could do was shut my eyes and think of cool sea breezes. It worked.

The Alcor reception area is done up in grays, icy whites and shiny metals. This is a cryonics company. Its two most obvious and predominant negative images to overcome are death and the cold.  I didn’t really need the rest of the tour because even before the nausea had fully subsided, I realized that the special expertise Max had been hired to ply on Alcor was a new, high technology “preservative” skill called techsodermy, which is the cryonics equivalent for “dead” high technology companies. It was invented in the 1980s in Silicon Valley, and while I just made the analogy to cryonics, it really owes it origins more to taxidermy, because it was invented in order to fill dead tech companies with fluff in the hopes of convincing someone to buy them. (When we were waiting for our rides, the Merkeley Lady said the lobby reminded her of Benihana, and that she expected an “Oriental gentleman” with sizzling liquid nitrogen and  steak and shrimp to come out and start “chopping our meal” with a Ginzu knife at any moment. At least, she hoped it was steak and shrimp.)

My Old Man is all about money. In fact, he is money. He makes money appear and disappear. He moves money. He cleans it, he packages it, he inventories it, he “handles” it. That means that his clients are, mostly, people who rarely, if ever touch the filthy stuff. Some of them don’t even want to touch the little pieces of plastic that serve as markers for it. It’s an irony that the people who have the most money are the most visibly invisible of the super rich. If there is anyone reading this who knows what a Smythsons Diary is, I’d be very surprised. Perhaps a few more would know how to assess a man’s station by looking at his shoes, or his writing utensil? Today, casual dress is so commonplace and so comfortable…and if you want to be somewhere reasonably economically and you have commonsense and a lot of money, you book first class and you dress sensibly and comfortably. But, if you are in the know – then you know who’s who, and you don’t need a ledger book to tell you.

If you want peace and privacy, then you don’t travel by commercial means at all. That’s for the peasants. You use Flight Centres and privates jets, and there is no security screening. And if you want a blow job or a massage, or both en route, that can be arranged for a few hundred dollars more; a small part of the cost of coach ticket the flying public pays, and that after taking off their shoes and belts and switching planes in Houston and Dallas.

The people at Alcor are clueless about how to get the customers that matter. Not just the rich and the super rich (the people my Old Man services day-in and day-out), but the “good-judgment” segment of every demographic of the population. You may be a working class stiff from Boston in a cloth coat, but you know what the genuine trappings of quality, durability and class are, regardless of the style. Warmth, wealth, style, elegance, quality; whether understated or overstated, they always come through. So does Costco warehouse gray.

My Old Man wanted me to get an M.B.A. But he wasn’t altogether disappointed that instead of the usual frequent flier card I got that Mark IV. He’s interested in cryonics and he thinks it has a technical and (less so) a financial chance of working. But Alcor? I may be that desperate, but unfortunately for me (and him), he’s not.
