Not to get too far off topic, but...
I heard a true story that your soul lives on though your body is left to rot.
A scientist wanted to find out if there really is a soul. So by luck, he managed to find a dying man at a hospital. He took the man and put him on a scale. The man was nearly about to die and the scientist recorded his weight. When the man passed away, the scientist looked at the scale once more and saw the weight had dropped half a pound.
But this story has been heard by many critics and other scientists. Maybe the man just farted or something. Who knows?
The man was Dr. Duncan Macdougall who, in 1907, took several people (I think it was 6 of his patients) who were dying of tuberculosis and put them in beds attached to big scales and watched to see the if the weight changed when the people died. The dead apparently did loose a tiny bit of weight, but the reasons for that weight loss were hotly debated by other doctors at the time and nowadays I don't think anyone takes the idea seriously.
The good doctor also repeated the experiment with 15 dying dogs. He reported that they didn't loose any weight when they died.
