Suspended animation

Suspended animation is the slowing of life processes by external means without termination. Breathing, heartbeat, and other involuntary functions may still occur, but they can only be detected by artificial means. Extreme cold is used to precipitate the slowing of an individual's functions. Although the technique has not been applied to human, experiments are successful in dogs, pigs and mice. Scientists drain the blood from animals' bodies and put an ice-cold solution into their circulatory systems. After being clinically dead for three hours, their blood is put back into their circulatory systems, and the dogs are revived by delivering an electric shock to their hearts. Scientists also have done similar experiments on pigs and tested 200 times with a 90 percent success rate. There are also experiments reports success towards inducing suspended animation in mice by using chemical method, according to an article published in the scientific journal Science on April 22, 2005
