All true and just for the record, my first sentence was actually based on a comment that a doctor once said to me. (And I realize that doctors are people, too, and can absolutely be wrong.) He told me a smoker who eats right and exercises regularly is going to be in better general health than a non-smoker who never exercises and has a trash diet. (He also told me he smoked all the way through medical school, so there's that. I think he was trying to reach me when lecturing me that I needed to quit and assuming I would think he didn't know just how hard quitting was. I dunno.) Nice guy, though. I think he'd be happy to know that I finally did quit.
"Duh, experts. What do dey know?"

Now to be fair, I used to concur even with the first sentence, nor should it be taken that I'm minimizing one at the expense of the other. But then it sort of came up in several contexts and I modified my statement in agreement with those (which to be fair - you did as well).
My favorite - which 92 sorta showed - is the always preposterous "appeal to one person" fallacy, and here I WILL say that smokers at least in my experience are BY FAR the worst at "well, I had a cousin who didn't smoke and he died at 49 while his brother smoked like a chimney and lived to 98" (drinkers are a distant second in this one). It's like saying, "I knew a guy who had a wreck and the only reason he lived is he wasn't wearing a seatbelt and it threw him clear of the crush in the driver's seat." YES - that happens on rare occasions. But you never see these same individuals pull their life savings out of the bank, go to Vegas and put all the money on one roulette number because it happens.
Why not? Because odds are against it - just like with the seat belt.
On the other hand...as the late Tim Wilson said:
"Roosevelt smoked, Churchill smoked, Eisenhower smoked, and Douglas MacArthur smoked.
TOBACCO WON WORLD WAR TWO!!
Then we started smoking reefer and Vietnam and got our...."
