When an animal is appeared to be dead and then wakes up without any harm, is suspended animation.. that is funny how he said that you aren't dead unless you're warm and dead. Some people have been frozen and no heartbeat, and came back to life after she was warmed. It would be cool in the future we can freeze ourselves and at a certain time we can come out and scare people... They are actually experimenting with animals on the suspended animation in labs. It is only six hours though right now. When you have this chemical, hydrogen sofhyde, in your body, it decreases the chance to have a heart attack. It is not lethal.. they are now on human trials of this experiment. This would be a great thing for the people in the future.
