Gee, my Mom smoked and lived to be 91. I don’t think she would have wanted to be 105.
Excellent....I hope my mom can make it that long.
Now, I would not go to someone and tell them not to smoke. I really don't give a darn what someone else does with their own body (although if it was an enclosed space, and after telling the person to stop twice they still continue, my second request would definitely be a smash to the person's face. That is one of the few things I have no tolerance for). Thus, if someone else wants to smoke they can go ahead and puff all day long.
However, smoking for the average person is one of the most imprudent courses of action healthwise one can take. While there are outliers (people who chug every day and have perfect health), the average person gets hammered eventually.
