I have been smoking since I was 5 years old. I could read the warnings at that age but no one jumped in saving lives then. I know people who have died of cancer and were never around cigarettes or smoke their entire lifetime. Yes I have asthma, but I also worked around flour from bakeries and dust from newspapers and the smells from colognes. I was 53 in October and there is no difference in my breathing other than when I am around someone that smells heavily of perfume.
