A woman was walking down a residential street and saw a frail, wizened old man rocking contentedly in a chair on his porch. She called out to him as she passed by, "Hello there! I couldn't help but notice how happy you look. Tell me," she said, "what's your secret for a long, happy life?"
"I smoke three packs of cigarettes a day," he replied. "I drink a case of whisky a week, eat nothing but fast food, and never, ever do any exercise."
"Wow!" said the woman, "that is amazing. That must really make you happy! And just how old are you?"
"Twenty-six," he replied.
