I’d live to be a hundred

A man asked his doctor if he thought he'd live to be a hundred.
The doctor asked the man, "Do you smoke or drink?"
"No," he replied, "I've never done either."
"Do you gamble, drive fast cars, and fool around with women?" inquired
the doctor.
"No, I've never done any of those things either."
"Are you a Christian or some kind of a religious person?"
"No, I don't believe in anything."
"Well then," said the doctor, "what do you want to live to be a
hundred for?"
