No, I don't, and I can't remember anyone in my family ever smoking except my grandfather, who died of heart disease at age 64. I was 5 years old.

My husband is a severe asthmatic and our doctor says that he has the lung capacity of a 3 pack/day smoker, but he has never smoked. He grew up in a house full of smokers, though.

PS. Good for you who have quit or are thinking of doing so.
