Hibernating Humans

Jim Clearman and I talked about this stuff years ago. I'm curious to see if this pans out, as it would be of huge benefit, having both medical and recreational uses. I guess it would benefit famine management, too. Plus, if you were dying, and just HAD to stay alive long enough for the next Harry Potter movie (or a child's wedding, etc), you could prolong your life down at "Crazy Jim's Hibernation Haven".
