Depressed Metabolism

Advocates of human cryopreservation argue that death is not an event but a process. Cryonics patients are stabilized at low temperatures in anticipation of a second medical opinion in the future. This raises an important ethical issue. What is the moral status of cryonics patients? It is not possible to argue that cryonics patients will [...]

There are various competing strategies how to achieve meaningful life extension or rejuvenation, including , but not limited to, genetic manipulation, periodical elimination of damage, caloric restriction,  molecular nanotechnology and mind uploading. A useful review of these strategies has been published in the book The Scientific Conquest of Death: Essays on Infinite Lifespans (2004) by [...]

Mind uploading advocate Kenneth Hayworth has launched an interesting website devoted to the science of brain preservation. Of particular interest is his Proposal for a Brain Preservation Technology Prize (PDF). This document includes one of the most comprehensive discussions of chemopreservation as a strategy for personal survival. For example, one of the most common objections [...]

William Faloon is a Licensed Funeral Director and Embalmer (Florida license number: F042784)
Human beings are largely unaware about the gruesome nature of “death”
Humans also shy away from the mutilation that occurs during hospital surgery.
Hollywood films portray cryonics in a glamorous high-tech manner that makes it appear that one’s body can easily be placed into a [...]

One question that is going to be of great interest is how aging baby boomers will confront aging and death. Where previous generations have found peace in religion and silent resignation, there are reasons to believe that this generation will not be so complacent. The baby boom generation, or at least those who have shaped [...]

This past weekend Motel X, the Lisbon (Portugal) International Horror festival, had its third anniversary. It is one of the smaller international horror festivals around, but this year they managed to have both Stuart Gordon, director of several Lovecraft adaptions, and John Landis, director of the horror classic An American Werewolf in London, as special [...]

The 2008-3 issue of Alcor’s Cryonics Magazine contains a number of articles about the pitfalls of (excessive) scientific optimism and its potential adverse effects on the organizational and practical aspects of cryonics. My own contribution contrasts cryonics as medical conservatism with the kind of scientific meliorism that is often associated with movements such as transhumanism [...]

When I was in New Zealand in 1999, CI Member Cam Christie told me that one of his co-workers was against cryonics because she was a Jehovah’s  Witness and her church had a position against cryonics. I recently found an article about cryonics on the Jehovah’s Witnesses website:
The piece contains the statement:
“…the use of nanotechnology [...]

The cryonics organizations Alcor and the Cryonics Institute have taken great care to correct some of the persistent myths about cryonics. With so much widespread misinformation being circulated in the media it seems trivial to pay attention to some of the misconceptions that some people who are sympathetic to cryonics hold. But the price of [...]

This is the eighth entry in a series about resuscitation of non-hibernating rodents from circulatory arrest at ultraprofound hypothermic and high subzero temperatures. In 1982, P.D. Rogers and G.P. Webb published some of their observations (based on previous papers and a Ph.D thesis) after carrying out a classroom demonstration of suspended animation in which they [...]

This is the seventh entry in a series about resuscitation of non-hibernating rodents from circulatory arrest at ultraprofound hypothermic and high subzero temperatures. After spending a few years on perfecting on Andjus’ technique for resuscitating rodents (rats and hamsters) from ultraprofound hypothermic and high subzero temperatures, Audrey Smith upped the ante and attempted the same [...]

This is the sixth entry in a series about resuscitation of non-hibernating rodents from circulatory arrest at ultraprofound hypothermic and high subzero temperatures. After successfully reanimating rats from deep body temperatures of 0 – 2 degrees C and subsequent respiratory and cardiac arrest, Andjus allowed the survivors to live for many months afterward in order [...]

This is the fifth entry in a series about resuscitation of non-hibernating rodents from circulatory arrest at ultraprofound hypothermic and high subzero temperatures. As we have seen, Radoslav Andjus had determined a method for achieving excellent (75-100%) recovery rates in rats cooled to 0-2 degrees C by local cardiac heating prior to warming the whole [...]

Robert J. White is most known, or perhaps most notorious, for his work on primate head transplants. Less known, but more relevant to the practice of human cryopreservation, is his work in cerebral ischemia, hypothermia, and brain preservation. Most of White’s innovative work was published in the 1960s and 1970s. White also published a substantial [...]

This is the fourth entry in a series about resuscitation of non-hibernating rodents from circulatory arrest at ultraprofound hypothermic and high subzero temperatures. Up to this point we have discussed the groundbreaking research in the early 1950s performed by Radoslav Andjus in resuscitating rats from body temperatures between 0 and 2 degrees C. Having determined [...]

This is the third entry in a series about resuscitation of non-hibernating rodents from circulatory arrest at ultraprofound hypothermic and high subzero temperatures. Andjus and Smith were delighted that they had managed to modify Andjus’ chest-wall heating technique from using a hot metal spatula to using a focused beam of light in order to preferentially [...]

This is the second entry in a series about resuscitation of non-hibernating rodents from circulatory arrest at ultraprofound hypothermic and high subzero temperatures. As discussed previously, in 1951 Radoslav Andjus developed a simple method for resuscitating rats cooled to deep body temperatures between 0 and 2 degrees C which involved applying a hot spatula to [...]

This is the first entry in a series about resuscitation of non-hibernating rodents from circulatory arrest at ultraprofound hypothermic and high subzero temperatures. Prior work in hypothermia began in the early 1900s, but because cardiac and respiratory arrest were observed in the animals around 15 degrees C, researchers assumed they were irreversibly dead [...]

“Buddhism and Epicureanism combat the fear of death by accommodating the emotions to the reasonable certainty of death. Contemporary immortalism (which includes projects such as life extension, cryonic suspension, and universal immortalism) argues that scientific and technological solutions to the problem of death can be found, thus questioning the inevitability of death. Buddhist, Epicurean, and [...]

James Warren is to be complimented for writing a thorough and persuasive book on Epicurean thinking about death. In Facing Death: Epicurus and his Critics, Warren offers a detailed review of Epicurus’ view that “death is nothing to us.” His treatment of Epicurus’ critics should be considered a success for the following three reasons. The [...]

It’s difficult to follow up a best-selling book about the cultural history of the penis, but David M. Friedman has a knack for engaging readers in topics that others find difficult to broach. This time he tackles the touchy subject of death by relating the intertwined biographies of Charles Lindbergh and Alexis Carrel in [...]

The website TopTenz recently published a list of the Top 10 Most Famous Preserved Body Parts. The list includes Galileo’s finger and Albert Einstein’s brain. As has been discussed on this blog before, the preservation of human brains (no matter how frivolous the intention) raises a number of important questions about the nature of death [...]

In 2003 George Hart published an article called “The Immortal’s Dilemma: Decontructing Eternal Life” , making a secular case against immortality.  Hart mainly uses logical arguments and provides a fair amount of room to address a number of possible objections to his position. In a nutshell, Hart considers two variants of immortality, one without [...]

The idea that death gives meaning to life is widespread but does not reflect careful reasoning, and is often a  desperate rationalization of human mortality. As a consequence, life extensionists have not been at great pains to defeat “pro-death” arguments. A (secular) philosophical position that is harder to refute is that we should not fear [...]

In 1991 the Libertarian Alliance published an article called “Immortality: Liberty’s Final frontier” (PDF) by David Nicholas. In this article the author argues that “the continuing fact of death renders all talk of liberty ultimately futile.” The author further argues that our concern for the future will diminish as we approach death. But instead of [...]

The blog Grim Reviews draws attention to a new interview with horror writer Thomas Ligotti, one of the most important writers of bleak fiction since Edgar Allan Poe and H.P. Lovecraft. In this interview, Ligotti talks about his upcoming book The Conspiracy Against the Human Race: A Short Life of Horror. In this book, the [...]

If immortality means a zero chance of death, it is doubtful whether mankind (or any lifeform) will ever achieve this. Nevertheless, advocates for extending the maximum human life span often face arguments that address the negative features of being immortal. It is important to be aware that arguments against immortality do not necessarily apply to [...]

Edvard Munch’s painting “Death in the Sick Chamber” (1895) portrays death as expressed through the survivors. A striking aspect of this work is that all the people in the room do not console one another and are physically and emotionally isolated.

In “Modern Art and Death”, Carla Gottlieb writes:
….the faces are contorted, not in mourning for [...]

In the future, Carl C.G. Jung may not be so much remembered for his contributions to science as for his beautiful writing, imagination, and wide range of interests. In his meditation on death, “The Soul and Death” (“Seele und Tod”), Jung treats death as the inevitable descent after an ascent up a hill. Jung’s stoic [...]

Just a superficial look at the history of the life extension movement will suffice  to show the rise and fall of numerous fads and trends in ideas about the mechanisms and “treatment” of aging.  Psychological meliorism and simplistic visions of biochemistry create overly optimistic expectations about extending the maximum human lifespan.  But how can we [...]
