A walker noticed an old lady sitting on her front step, so he walked up to her and said, "I couldn't help noticing how happy you look! What is your secret for such a long, happy life?"
"I smoke ten cigars a day," she said. "Before I go to bed, I smoke a nice big joint. Apart from that, I drink a whole bottle of Jack Daniels every week, and eat only junk food. On week-ends, I pop pills and do no exercise at all."
"That is absolutely amazing at your age!", says the walker. "How old are you?"
"Twenty-four," she replied.
