A young man fell into a coma but regained consciousness just as his friends were about to bury him. One of them asked what it felt like to be dead.
"Dead!" he exclaimed. "I wasn't dead. I knew I wasn't because my feet were cold and I was hungry."
"But how could you be sure?"
"Well, I knew that if I were in heaven, I wouldn't be hungry, and if I were in the other place, my feet wouldn't be cold."
