secret of long life

A doctor on his morning walk noticed an elderly lady sitting on her front porch step smoking a cigar,
so he approached her and said, "I couldn't help but notice how happy you look! What is your secret?"
"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 weekends, I pop some pills, get laid, and don't exercise at all."
"That is absolutely amazing, he said, "How old are you?"
"Thirty-four," she replied.
