My mom died from emphysema and was totally addicted to smoking. Near the end, walking around pulling a little portable oxygen tank, she said she'd rather smoke than breathe.
Funny, both my parents smoked like chimneys most of their lives and I've never smoked a day in my life except for a few of those "funny" cigarettes when I was trying to talk some girl out of her pants.
I'm not a big anti-smoking fanatic though, I don't like telling people what to do or how to live. I don't want people smoking on planes or next to me in a restaurant or in the movies, but that's about it. I hate self-righteous busy body fascists. Freedom is the most important thing in the world to me.
Mine did too, as did my grandmother, and I would not wish that or lung cancer on anyone. I do however see some irony in the fact that she wanted to control my gun while she could not, or would not, control her own smoking.
