Cryonics is the science of low-temperature preservation of humans and animals.  The premise of Cryonics is to preserve the individual, and in particular their brain, for a future time where the subject’s health problems can be cured by medical science. In the US, all individuals must be legally declared dead prior to being frozen through the Cryonic process.  There are currently two major organizations offering cryonic services in the US, and only time will tell whether their client will benefit from this form of suspended animation.
