My grandmother hasn't smoked in 40 years, she defends smokers rights to smoke. I've got an uncle on my dad's side of the family that hasn't smoked in 25 years and he defends smokers rights to smoke. My folks and I both smoked for years (I smoked for over fifteen years) and nothing annoys me more than a Cig Gnatzie.
I had a father-in-law who suffered from emphysema,
but I think he died of a heart attack, which was,
of course, brought on by the emphysema. I recall
that he was hooked to oxygen for the last two years of his life.
