A young man fell into a state of coma, but recovered before his friends had buried him. One of them asked what it felt like to be dead."Dead!" he exclaimed. "I wasn't dead. And I knew I wasn't, because my feet were cold and I was hungry.""But how did that make you sure?""Well, I knew that if I were in heaven I shouldn't be hungry, and if I was in the other place my feet wouldn't be cold."
