Scientists have been able to induce hibernation in mice. Using hydrogen sulphide they were able to slow down the metabolic rate of the mice. Later the mice were brought back using plain oxygen. It’s been speculated that this technology could be used by astronauts on long space flights or as my title suggest just living longer for everyone. If you don’t want to wait just buy a sleep chamber from Aliens , throw in some rotten eggs and you’re good to go.
