paragraph_text: Cryonics
  
  Cryonics (from Greek κρύος 'kryos-' meaning 'icy cold') is the low-temperature preservation of animals, including humans, who cannot be sustained by contemporary medicine, with the hope that healing and resuscitation may be possible in the future.
  
  Cryopreservation of people and other 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 generally regard cryonics with skepticism.
