Who wants to live for 100 years !

A 60-year-old man is getting his annual physical:
- Doc, do you think I'll live another 40 years so I can reach 100?
- That depends," says the doctor. Do you smoke?
- No
- Do you drink?
- No
- Do you fool around with loose women?
- Of course not
- Well, then, why the hell do you want to live for another 40 years?
