How do hibernation/aestivation happen?
I read on wikipedia that a squirrel injected with the body fluids of a hibernating fellow is more prone to hibernation. If hibernation/aestivation are driven by biochemicals and not merely the weather, can the process be induced in higher beings such as humans to replace surgical (etc) anesthesia? How is the one different from the other?
