A man asks his doctor: “Do you think I’ll live to be a hundred?”
The doctor asks the man “Well, that depends. Do you drink?”
“Oh, no sir! I abstain from all alcohol. Soda, too. I just drink plenty of fresh water. “
“Do you smoke?”
“No, sir! Never smoked in my life, and I stay away from any place with second hand smoke. “
“Do you eat a lot of sugary and greasy foods?”
“No, sir! I carefully watch my diet and caloric intake, and I’m sure to eat plenty of vegetables. “
“Do you go to parties? Stay up late? Are you sexually promiscuous?”
“Not at all! Early to bed and early to rise! And abstinence is key. “
The doctor raises an eyebrow at the man. “So… Why exactly do you want to live to be a hundred?”
