Cryonics

That is not dead that can eternal lie,
and with strange aeons even death may die.
H. P. Lovecraft
Centuries march by
unknown, unknowable
from my frozen slumber
Mark Dowdey

While most transhumanists are quite convinced that life extension will be possible, most agree that it will take several years (or decades/centuries) before immortality becomes practical. And in the meantime there is a non-zero chance that you die from accidents or disease, regardless of how healthy your lifestyle is.

One answer to this problem is cryonics, or rather cryonic suspension; the technique of freezing the body to so low temperatures that it does not decay significantly. If misfortune strikes, you could be suspended until medical techniques have been developed far enough to revive you and cure you.

Cryonics is currently a big gamble, and even the enthusiasts acknowledge that there are many unsolved problems. But there is little to loose by choosing cryonic suspension: either it will work and restoration methods will be developed and used in the far future, or it won't:

You are suspended You are not suspended
Cryonics Works You Live You are dead
Cryonics Doesn't Work You are dead You are dead

So the rational choice is to use cryonics, even if success is improbable, unless you consider the value of your life times the chance that it might work to be less than the cost of a suspension.

Cryonic Suspension by Henry Kluytmans. An overview of the arguments for cryonics and answer to some common questions.

Problems

Cryonics and Overpopulation. One of the most common arguments against life extension and cryonics is the risk of overpopulation. This posting shows why this isn't a real problem.

MADison Avenue Meets Cryonics? by Kevin Q. Brown. About the problems and techniques for marketing cryonics.

Frozen Souls: Can a religious person choose cryonics? by Stephen Bridge. Cryonics tends to raise religious questions, often confusing the issue.

LifePact. One common argument against cryonics is that there is no guarantee for being revived by future humans. LifePact is a network for suspendees that will seek to revive each other when possible in order to increase the chances of revival. See also cryonet postings on the subject.
