This actually reminds me of something I was thinking about a couple days ago. You know how people can be resuscitated after hours with their hearts stopped, if they were in near-freezing conditions? Like people who have drowned in frozen lakes and then been brought back hours later? Someone coined the phrase, "You're not dead until you're warm and dead." Well, I wonder if that could be done long term. I'm guessing all the body's processes would be dramatically slowed in such a scenario, giving similar benefits to cryopreservation. Presumably it would come with many new problems (I doubt the brain would survive long term like that without at least some circulation of oxygenated blood for starters), but it's at least conceivable those would be easier to solve than the problem of freezing and thawing a body without irreversible damage.

- sigmar 4y agoThere are a bunch of examples of that (mostly referred to as suspended animation) and a few that even have been covered in medical journals. There are examples on wikipedia[1]. I researched it as a topic for a very strange class I took in college and remember there were more than a few gov't research projects (DARPA and others) trying to achieve various means of suspended animation for military and space applications. 1. https://en.wikipedia.org/wiki/Suspended_animation#Basic_principles https://en.wikipedia.org/wiki/Suspended_animation#Basic_prin...
