A woman walks up to an old man sitting in a chair on his porch.

"I couldn't help but notice how happy you look," she said.

"What's your secret for a long, happy life?"

"I smoke three packs a day, drink a case of beer, eat fatty foods, and never, ever exercise," he replied.

"Wow, that's amazing," she said, "How old are you?"

"Twenty-six."
