>What about those of us who don't smoke? I gave up competitive bridge about a year after I quit smoking myself; the air in a room with a bunch of people smoking cigarettes, pipes and cigars develops a blue haze and rapidly becomes stifling. It wasn't worth making myself ill to spend the day playing cards...

As a reformed smoker (15 years now), I see you know what I mean when I say I had no idea how bad the air was in those smoky rooms I frequented until I had quit...it's a real mind-opener.
