An Hour Before Daylight. by Jimmy Carter: on Drugs

Never smoked; parents and siblings all died of cancer

"Yes, sir, Daddy."

"I don't want you to smoke a cigarettes until you are 21 years old."

"No, sir, Daddy, I won't."

He then made an unnecessary commitment. "When the time comes, I'll give you a gold watch."
