When I reported on people in nursing homes for various stories, I used to love to watch the really old folks puffing away at outside tables (I was a smoker myself at the time).
Even with their wildest claims, anti-smoking zealots say about 50% of smokers die of a smoking-related disease or condition. That means half do just fine
through old age, until the bitter end. I smiled when I saw the "safe" half.
And you know what that means? Some people have great genes, bubba.
