I didn't just grow up in a house of smokers, I grew up in a house of CHAIN smokers. The consequences? Well, both of my parents have severe emphysema, my Dad is on an oxygen tank, and THIS makes you wonder long and hard. As a child, I always promised my parents I would one day become the president of the American Lung Association. If I didn't have enough motivation to do so before, I might now.
(dang. the above article got pulled. in short, it was a study linking second hand smoke exposure as a child/young adult to both infertility and miscarriage)
