The notion of human hibernation or “suspended animation” has been used often in science fiction. Hell, I bet if you tried not very hard, you could probably come up with a dozen examples of such technology being used in various sci-fi stories.
However, as science progresses, the possibility of science fiction becoming science fact increases.
Toien said the hibernation trick would come in handy in outer space as well — and not just for long bouts of suspended animation, such as those depicted in “2001: A Space Odyssey” or the movie “Avatar.” Toien noted that bone loss and muscle loss is a problem right now for long-term spacefliers on the International Space Station.
One of the takeaways reading this is that scientists have found that hibernating bears do not loose bone density or muscle mass.
Wrap your imagination around that.
