Quit cold the second time in 1982. But I smoked like a fiend before all that, since 1961. So far so good on the lung stuff, though I've long had, mmmm, vasomotor rhinitis, and a kind of reactive asthma... probably starting around 1961 as well - but, again, so far, so good.
Sadly, my allergies improved when I no longer had cats around and we remodelled. I do like cats a great deal, but have to steer clear.
On smoke, yes, it gets my nose running and asthma perking up. Frowns at Dys.
Well, no, I'm not really frowning at Dys on the cigs now. That's another whole subject, but I need to keep clear of smoke myself.
