New submitter Budgreen writes: "Knife-wound or gunshot victims will be cooled down and placed in suspended animation later this month. The technique involves replacing all of a patient's blood with a cold saline solution, which rapidly cools the body and stops almost all cellular activity. 'If a patient comes to us two hours after dying you can't bring them back to life. But if they're dying and you suspend them, you have a chance to bring them back after their structural problems have been fixed,' says surgeon Peter Rheeat from the University of Arizona in Tucson, who helped develop the technique. 10 gunshot and stabbing victims will take part in the trials."
We warn the reader in advance that the proof presented here depends on a
clever but highly unmotivated trick.
