A few years after his wife died, John decided to go to the doctor for a physical. When he went to the doctor the doctor asked him a lot of questions. John said he wanted to live to be 100 and wanted a check up. The doctor asked John if he smoked. John said no. The doctor then asked if he drank. John said no. Lastly, the doctor asked him if he stayed out late at night carousing with loose women. John said no to that too. Then the doctor said if you don't do any of these then why in the world would you want to live to be 100?
