Frequently Asked Questions

Common sense answers to some of the most common questions about cryonics.

GENERAL QUESTIONS

Cryonics is a technique intended to hopefully save lives and greatly extend lifespan. It involves cooling legally-dead people to liquid nitrogen temperature where physical decay essentially stops, in the hope that future technologically advanced scientific procedures will someday be able to revive them and restore them to youth and good health. A person held in such a state is said to be a "cryopreserved patient", because we do not regard the cryopreserved person as being inevitably "dead".

Legally, not yet. Obviously, it would be better to cool a patient before illness causes so much physical damage that it results in death. But it's not presently allowed by law, even for someone in great suffering or with a terminal illness. We hope that one day it will be, under carefully controlled conditions, once revival from cryopreservation can be demonstrated.

We believe that revival is a real possibility because:

  1. Many biological specimens have been cryopreserved, stored at liquid nitrogen temperature where all decay ceases, and revived; these include whole insects, vinegar eels, many types of human tissue including brain tissue, human embryos which have later grown into healthy children, and a few small mammalian organs. Increasingly more cells, organs and tissues are being reversibly cryopreserved.
  2. The repair capabilities of molecular biology and nanotechnology increasingly point to a future technology that can repair damage due to aging, disease and freezing.
  3. Current progress in stem cell tissue regeneration, 3D biological printers and other advanced technologies provides encouraging promise that we might be able to revive people in a healthy and youthful state when these technologies mature.

Not to cryogenic temperatures. Dogs and monkeys have had their blood replaced with protective solution and cooled to below 0ºC, with subsequent rewarming and revival. Nematode worms have been cryopreserved in liquid nitrogen (−196ºC), and subsequently revived. At the July 2005 Society for Cryobiology Conference, it was announced that a rabbit kidney had been completely vitrified to solid state at −135ºC, rewarmed and transplanted to a rabbit with complete viability. Although a whole mammal has not yet been cryopreserved to cryogenic temperatures and revived, the progress of science is moving in that direction.

However, the cryonics theory does not depend on the status of current cryopreservation technology. Cryonics supporters believe that the damage caused by current cryopreservation can someday be repaired. Molecular repair technologies like nanotechnology give us hope that we can be revived through future technology that does not yet exist. Even though cryopreservation could potentially cause cellular damage today, we believe there will be means to repair that damage in the future.

The cryonic cryopreservation state is sometimes described as "cryonic suspension," because the patient's state is unchanging and therefore "suspended in time." However, cryopreservation is not "suspended animation" in the sense of being reversible by current technology.

We don't believe so. Cryonics is based on faith in emerging technologies that are in development today, including nanotechnology — the manipulation of individual atoms or molecules, which we believe will eventually allow mankind to build or repair virtually any physical object, including human cells and biological tissue.

One of the projected possible applications of nanotechnology is the repair of precisely the sort of damage to human tissue caused by freezing at liquid nitrogen temperatures — as well as cellular and organic damage caused by disease and aging.

When will that happen? Robert A. Freitas, author of three-volume text Nanomedicine — selections from which are available via our Links page — has publicly stated, "I would not be surprised if the first cryonics revival was attempted by 2040-2050." Of course, no one can predict such dates, and we don't rely on any particular prediction.

Dr. Ralph Merkle, in his essay 'The Molecular Repair Of The Brain', observes, "Interestingly (and somewhat to the author's surprise) there are no published technical articles on cryonics that claim it won't work...A literature search on cryonics along with personal inquiries has not produced a single technical paper on the subject that claims that cryonics is not feasible. On the other hand, technical papers and analyses of cryonics that speak favorably of its eventual success have been published. It is unreasonable, given the extant literature, to conclude that cryonics is unlikely to work."

Notable technical papers which provides scientific evidence for the feasibility of cryonics are: ANNALS OF THE NEW YORK ACADEMY OF SCIENCES; Lemler,J; 1019:559-563 (2004) and REJUVENATION RESEARCH; Best,B; 11(2):493-503 (2008).

Good news: you heard wrong! With CI, the minimum fee for cryopreservation at CI (which includes vitrification perfusion and long term storage) is $28,000 — a one-time fee, due at time of death. And though it can be paid in cash, usually a member has a life insurance policy made that pays the amount to CI upon death. However, a life insurance policy beyond this minimum amount is strongly recommended. A larger amount can be used to defray additional costs, including transportation (which is not included in CI’s base fee) or even a cryonics standby team to perform rapid cooling and cardiopulmonary support upon pronouncement of death. A term life insurance policy in the amount of the minimum fee often costs around $30 per month for a person starting their policy in good health at middle age.

Advice from an insurance professional is recommended before selecting a policy. Because of possible future price increases — or additional future services requiring additional payments — it may be prudent to buy more insurance than the absolute minimum required.

A person who wishes to become a Lifetime CI Member can make a single membership payment of $1,250 and doesn't have to pay any annual dues at all after that. If a new member would rather pay a smaller amount up front, in exchange for funding a slightly higher cryopreservation fee later on ($35,000), he or she can join with a $75 initiation fee, and pay annual dues of only $120, which are also payable in quarterly installments of $35. (And such a dues-paying member can upgrade to Lifetime Membership at any time, saving $7,000 and any dues ever again.) Members at a distance may have to pay local funeral director fees and transportation costs to Michigan to be cryopreserved. These payments are not made to CI, and are not included in the figures outlines above.

Prices vary greatly. CI has by far the lowest prices of any cryonics organization. Our procedures are deliberately cost-conscious, but they are based on proven experiments and professional evaluation, and in our judgment likely to give our patients the best chance possible for future recovery.

Prices with other organizations can be as much as $200,000 or more for whole body cryopreservation and $80,000 for a "neuro" (head-only) option. With CI, a whole body cryopreservation costs as little as $28,000.00, rendering an alternative "neuro" option unnecessary with regard to cost.

"Neuro" is short for neurocryopreservation, and it refers to the practice of removing and cryopreserving only the head of a person declared legally dead. The theory is that only the information contained in the brain is of any importance, and that a new body could be cloned or regenerated at some point in the future.

Neurocryopreservation requires less space and maintenance, and so costs less. But our price for whole-body preservation is already lower than what other providers charge for a 'neuro', so cost isn’t a factor. We do not offer the neuro option, largely because we are concerned about neuro's negative effect on the public’s perception of cryonics and, especially, because of the negative impact on the families of patients.

Journalists and horror novelists invariably have a field day with "frozen severed heads," and focus not on the scientific or humanitarian purposes of cryonics, but on sensationalizing cryonics as grotesque or ridiculous. Our policy to always preserve the entire body prevents anyone leveling those claims at CI. Our goal is to preserve and eventually revive people, so we avoid processes like neurocryopreservation that could damage or otherwise put a patient at risk.

If you have — or expect to have — sufficient assets in any form, we may be able to work something out. Our members include attorneys and estate planners who are no strangers to creative financing.

If by "dead" you mean "clinically dead", without heartbeat or breathing, then "raising the dead" is done every day, thousands of times every year, in hospitals all over the world. Cardiopulmonary resuscitation or CPR — developed in the 1950's — quite commonly restores life to people who were once considered (wrongly) to be absolutely and irretrievably dead, throughout all of previous human history. This technique is standard practice today.

If we can restore life to people who have been "dead" for several minutes, and even hours in some drowning cases, why should we assume that doing the same after years is impossible, if we can prevent further deterioration during that time?

"Absolute" death may only be said to occur when the brain's essential information is destroyed — and brain preservation is precisely what cryopreservation aims to achieve.

As for having a fatal disease — as science progresses, fatal diseases become formerly fatal diseases. Polio and bubonic plague were fatal diseases once; they — and hundreds of other diseases — are not fatal now. Many qualified people think that cures for currently fatal diseases — including old age — are only a matter of time.

It isn't necessary to wait until "every" disease imaginable is cured, all at one stroke. What you really need to do to make cryonics itself work is to cure or prevent freezing damage. Methods for reducing freezing damage including controlled cooling and vitrification are already in place, and we continue to make progress on many levels with ongoing research.

As improved cryopreservation methods, including improved methods of vitrification, are developed, there will be less burden on future technology, hence hopefully earlier revival. Vitrification means formation of a glasslike solid as temperature falls. This stops the formation of ice crystals that may damage tissues, thus reducing freezing damage. The Cryonics Institute vitrified its first human patient in the summer of 2005 (see The Cryonics Institute's 69th Patient).

Yes. See Scientists' Open Letter on Cryonics in which 60 eminent scientists affirm that "cryonics is a legitimate science-based endeavor". Note that cryonics is science-based, but cannot correctly be called current science. Cryonics is based on expectations of the repair capabilities of future science. The same could be said, for example, of possible human habitation of Mars. Both illustrate projecting future capabilities from the capabilities of current science.

No. Cryonics is a matter of rational procedure, not religious miracle. Cryonics can't restore life to people whose brains have been long been physically destroyed — a Lincoln, or a Julius Caesar, or those cremated. Cryonics simply — but reasonably — claims that if you cryopreserve a person in a way that limits damage, then that person's brain structure may be preserved sufficiently to make the eventual recovery of life and health at least possible.

And let's not be confused by language. "Dead" people — apparently dead people, no heartbeat or respiration — are revived every year, in hospitals all over the world, by the thousands. The dictionary definition of "death" is permanent cessation of vital functions. Therefore, if someone, even after cryopreservation, has recovered, that means the person wasn't "really" dead in the first place. We think that's the best way to look at it.

Sadly, we can't. No one can guarantee success, because no one can guarantee the future. No one can predict scientific progress with certainty, but we believe a strong case can be made for the probable success of cryonics. But that doesn't mean that social disruptions aren't possible. Nuclear war, economic collapse, political strife, terrorism, are all possible, and they could end the lives of cryopreserved patients just as easily as they can end the lives of those outside it.

One thing we can guarantee is that if you don't sign up for cryonics is that you will have no chance at all of coming back.

The oldest patient currently still being held in cryopreservation is a Dr. James Bedford, who was cryopreserved in 1967. He has survived the Cold War, the Vietnam War, the Gulf War, Watergate, the collapse of the Soviet Union and the 9/11 attacks — which is more than many of his contemporaries can say. The world is (relatively) stable at the moment, global world war doesn't seem likely, and the economy is relatively stable.

Again, we can't guarantee the future. But we can and do guarantee this: that at CI we will give our very best efforts to see our member patients are restored to life and good health. Because the life of every director and officer and member of CI depends on those efforts too.

MORAL AND ETHICAL QUESTIONS

Cryonics is strongly consistent with the pro-life views of Christianity and other religions that value the sanctity of human life. Noted Christian theologian John Warwick Montgomery has written favorably about cryonics ("Cryonics and Orthodoxy," Christianity Today, 12, 816 (1968)), there have been positive sermons about cryonics, and even one of the earliest cryopreservations in 1969 was consecrated by a Catholic priest (Cryonics Reports, Vol. 4, No. 9-10, 1969). Whenever negative views have been expressed, they are almost always based on the mistaken belief that cryonics is attempting resurrection. Cryonics is a form of life support, not resurrection. We expect that cryonics, like surgical suspended animation and hypothermia rescue, will eventually be fully embraced by Christians as it becomes clear that cryonics is simply another medical technology.
