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.”
“Well then,” said the doctor, “What do you want to live to be a hundred for?”
