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."
