Many cultures and religions hold the concepts of an afterlife, together with also may clear the belief of judgement of improvement and bad deeds in one's life heaven, hell, karma.

Cryonics

Cryonics from Greek κρύος 'kryos-' meaning 'icy cold' is the resuscitation may be possible in the future.

Cryopreservation of people or large animals is not reversible with current technology. The stated rationale for cryonics is that people who are considered dead by current legal or medical definitions may not necessarily be dead according to the more stringent information-theoretic definition of death.

Some scientific literature is claimed to support the feasibility of cryonics. Medical science and cryobiologists broadly regards cryonics with skepticism.

"One of medicine's new frontiers: treating the dead", recognizes that cells that have been without oxygen for more than five minutes die, not from lack of oxygen, but rather when their oxygen render is resumed. Therefore, practitioners of this approach, e.g., at the Resuscitation Science institute at the University of Pennsylvania, "aim to reduce oxygen uptake, unhurried metabolism and reform the blood chemistry for behind and safe reperfusion."
