Boffins are not far away from sticking people in suspended animation.
Apparently a gas which is used in weapons of mass destruction might be a good candidate to shove people into life-saving suspended animation.
Hydrogen sulphide is toxic in large doses, but small amounts of the gas can make animals appear dead for a while then allow them to wake up unharmed.
Biochemist Mark Roth, from the Fred Hutchinson Cancer Research Center in Seattle, said that in the future an emergency medical technician might give hydrogen sulphide to someone suffering serious injuries and they might become a little more immortal giving them time to get the care they need.
Suspended animation takes place in the natural kingdom, with bears hibernating through winters while plant seeds and bacterial spores are able to biologically snooze for millions of years.
Roth found that hydrogen sulphide bonds at spots in bodies that would usually be occupied by oxygen.
He did it to a mouse and all you had to do was put it in room temperature and it was no worse for the wear. So far he has not tried it out on a human yet.
