When my Great-grandfather was about 70 years old, he went to a new doctor for his annual physical (he'd outlived his last Dr.) The new doctor told him he was in great shape but that he should stop drinking and give up his pipes. Gramps laughed at him and said "I've outlived 6 doctors and I'll outlive you too."
I'm not sure if he outlived the doctor, but he made it to 88, always had a glass of bourbon in the evening and was never without a pipe.
