An elderly woman walked up to a little old man rocking in a chair on his porch. Though he looked weathered and feeble, he had a content smile on his face.

“I couldn't help noticing how happy you look,” she said. “What's your secret for a happy life?”

“Well, I smoke three packs of cigarettes a day,” he said. waving a wrinkled hand through the air, with a smoldering cigarette between his thumb and finger. “I also drink a case of whiskey a week, eat fatty foods, and never exercise.”

"“That's amazing!” said the woman. “So, how old are you?”

“Twenty-six.”
