Mr. Richard Overton is a 109-year-old war veteran. He drinks whiskey and smokes cigars practically every day, and he's still going strong. He even still drives himself around in an automobile.
With that said, "whiskey and cigars make you live longer" isn't necessarily the message that we should be taking away from Mr. Overton's story.
Another way of looking at this was put well enough by a commenter online:
"What I get from this is that you should do what makes you happy. He doesn't smoke or drink or even eat ice cream because it makes him live longer, he does it because it makes him happy, and that's what's most important."
