Reminds me of an old joke. A guy tells his doc that he really wants to live to be 100 and asks what his chances are. So the doc asks him some questions: Doc: "Do you drink?" Patient: "No." Doc: "Do you smoke?" Patient: "No." Doc: "Do you eat fatty foods?" Patient: "No." Doc: "Do you have multiple sex partners?" Patient: "No." Doc: "Then why do you care?"
