A woman walked up to a withered looking little old man sat contentedly on a park bench smoking his cigarette.
"I couldn't help noticing how happy you look," she said.
"What's your secret for a long happy life?"
"I smoke three packs of cigarettes a day," he said.
"I also drink a case of whiskey a week, eat fatty foods, and never exercise."
"That's amazing," said the woman, "how old are you?"
"Twenty-six," he said.
