- Section 9: Glossary
-
- (You can fetch cryomsg "n" by sending mail to kqb@whscad1.att.com or
- to kevin.q.brown@att.com with the subject line "CRYOMSG n". The index
- to this FAQ list is cryomsg "0018.1".)
-
- The next three sections have definitions of cryonics vocabulary. The
- list is divided (at the discretion of the editor) into words to use,
- words not to use, and words to use in jest.
-
- Words to Use
-
- CRFT has a glossary on pp. 57 - 58.
-
- biostasis - Synonym for "suspension".
-
- cardiac arrest - Cessation of heartbeat.
-
- clinical death - A person is clinically dead if they are in cardiac
- arrest and their pupils do not contract when light is shined into them.
-
- cryobiology - Biology at low temperatures. This includes organ preservation.
-
- cryogenics - Science in general at low temperatures.
-
- cryonics - The practice of freezing people at the end of their natural
- lifespan, hoping for eventual reanimation.
-
- information-theoretic death - A person has reached
- information-theoretic death if a healthy state of that person could
- not possibly be deduced from the current state. The exact timing of
- information-theoretic death depends on presently unknown details of
- how the brain works. The current best estimates put it several hours
- after clinical death.
-
- ischemia - Damage to tissues due to oxygen deprivation.
-
- legal death - A person is legally dead if a doctor has signed a death
- certificate with his or her name on it. This tends to happen when the
- doctor believes that modern technology will not be able to restore
- them to health. The criteria for legal death change with time.
-
- neurosuspension - The practice of only freezing a person's head or
- brain.
-
- revival - The process of restoring a clinically dead person to health.
-
- suspension - The process of preserving a person for eventual revival,
- usually by freezing in liquid nitrogen. This happens after legal
- death but hopefully before information-theoretic death.
-
- Words Not to Use
-
- corpsicle - Pejorative synonym for "suspended person".
-
- cryonicist - An ambiguous term. 1. One who studies or who tries to
- improve the process of freezing people for later revival. Use
- "cryonics researcher" instead. 2. One who is interested in cryonics.
- Use "cryonics fan" instead, or perhaps "person interested in cryonics".
-
- death - A vague term. Use "legal death", "clinical death", or
- "information-theoretic death" instead.
-
- deanimation - An ugly-sounding synonym for "clinical death".
-
- reanimation - An ugly-sounding synonym for "revival".
-
- Words To Use In Jest
-
- flexionally disabled - frozen stiff
-
- metabolically disadvantaged - clinically dead
-
- (Next five are from Alcor Indiana Newsletter #5 by Steve Bridge,
- cryomsgs 1148 and 1149.)
-
- chronologically gifted - old
-
- experientially enhanced - old
-
- achieved an overall metabolic deficiency - died, possibly frozen
-
- thermally challenged - frozen
-
- assumed room temperature - died, not frozen (Attributed to Rush Limbaugh)
