What is Cryonics?
{{distinguish|cryogenics|date=27 February 2019}} [[File:Cryo surgery.jpg|thumb|Cryonics]] '''Cryonics''' (from [[Ancient Greek|Greek]] ''kryos'', which means 'cold') is the process of [[:en:wikt:vitrifying|vitrifying]] a human (or animal) about {{convert|-196|C|F K|0|abbr=off}} after a [[Medical doctor|doctor]] says they are dead. People do that in hope that, in the future when medicine becomes better, they can have life again, solve their health problems and have [[Immortality|eternal life]]. Cold people like this are not awake at all as they have [[Brain death|no brain activity]]. The law also says they are dead. Their body and its brain are made more like [[glass]] than ice because ice would harm their cells more. To do this, their [[blood]] is replaced with [[chemical]]s called ''cryoprotectants'', which act like anti-freeze (something that stops freezing). == Companies == There are five big cryonics companies: # [[Alcor]], [[Arizona]], [[USA]]<ref>{{cite web|url=http://www.alcor.org/|title=Cryonics: Alcor Life Extension|access-date=2019-04-04}}</ref> # [[Cryonics Institute]] (CI), [[Michigan]], [[USA]]<ref>{{cite web|url=http://www.cryonics.org/|title=Cryonics Institute|access-date=2019-04-04}}</ref> # [[American Cryonics Society]] (ACS), [[California]], [[USA]]<ref>{{cite web|url=http://www.americancryonics.org/|title=American Cryonics Society|url-status=dead|archive-url=https://web.archive.org/web/20120202172132/http://www.americancryonics.org/|archive-date=2012-02-02|access-date=2019-04-04}}</ref> # [[KrioRus]], [[Russia]]<ref>{{cite web|url=http://www.kriorus.com/en|title=KrioRus - the first cryonics company in Eurasia|access-date=2019-04-04|archive-date=2016-07-08|archive-url=https://web.archive.org/web/20160708031938/http://www.kriorus.com/en|url-status=dead}}</ref> #[https://tomorrowbiostasis.com Tomorrow Biostasis, Germany] == References == {{reflist}} == Other websites == * [https://waitbutwhy.com/2016/03/cryonics.html Why Cryonics Makes Sense - Wait But Why] * [https://youtube.com/watch?v=F-3F9
