What is your secret?

A doctor on his morning walk noticed This old lady sitting on her front step smoking a cigar so he walked up to 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 pills, get laid, and don't exercise at all."


'"That is absolutely amazing! How old are you?"

"Thirty-four," she replied.
