An elderly guy goes to the doctor. The doctor tells him " Your blood work is all O.K. and you are in reasonably good health for your age."
The guy isn't satisfied with this. " My health is O.K.? That isn't what I wanted to hear. I want to live for a very long time."
Doctor asks " Do you drink alcohol? "
Patient " No"
Doctor "Do you eat red meat"
Patient "No"
Doctor "Do you smoke or use any tobacco products?"
Patient "No"
Doctor "Do you take any recreational drugs?"
Patient "No"
Doctor " Do you have a lot of hobbies; hunt, fish, play golf? "
Patient "No"
Doctor " Then why do you care how long you will live? "
