Zapol and colleagues report in this month's Anesthesiology journal about how hydrogen sulfide -- the same stuff produced by rotten eggs and swamp gas -- slows mouse metabolism without cutting blood flow to the brain.

"I don't know what it's like," he added, "probably some slow-motion world."

Some months ago I also found something about hibernation of pigs... So: pigs, mice, ... they are getting close to us! :D
