Heh Heh. The only thing most are even close to being made to breath are the fumes from car exhausts and gas pumps, all of which probably contribute to cancer they say. But then again, everything seems to cause cancer. I don't know any smokers personally that have had cancer, but have known several who were not smokers (and health nuts to boot) and died of cancer.
Some would say, why increase the risk, to which I say If we want to decrease the risk ya better be looking at living with the Amish.
We're all going to DIE!!!!!!
And there's not much anyone can do about it!!!!!
Run for your lives ...er...deaths!!!!
