Only as old as you feel

A passer-by noticed an old lady sitting on her front step:

“I couldn’t help noticing how happy you looked!  What is your secret for such a long, happy life?”

“I smoke 4 packs of fags 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 a huge number of pills and do no exercise at all.”

“This is absolutely amazing at your age!”, says the passer-by.  “How old are you?”

“Twenty four”
