Weirdly, my father who has smoked (and drank) daily his entire life (now 78), is still alive and kicking. Camel unfiltered and a lot of vodka.
I never smoked and I was never a big drinker. But, I stopped drinking entirely a couple years ago cause it was just too painful to look at him with his current health issues, and think to myself that I'm going to end up like he is. No thanks, I don't need that poison.
