I remember my uncle was a heavy smoker - got emphysema and would still smoke till his dying day. I remember walking in and seeing him remove his oxygen mask to inhale a smoke .... so sad ... would probably still be with us had he not smoked... but hindsight is always 2020 [/quote]
Likewise my Dad, emphysema and smoked 'til he died (aortal aneurism), but he refused to use oxygen because he believed it would make his lungs atrophy (as if they weren't already doing that!).

I visited the radiation center the other day and in the patient's parking next to me was a vehicle with the ashtray literally overflowing with butts.

Back when I smoked (for eight years), I tried ripping the filters off some cigarettes and they sure tasted nasty compared to those blended to be without filters.
