I dont have "links". I have a family member dying of it. I wish you had one also so you would know for yourself. I am sure that does not offend you since you dont care.Guess what?
My father died of smoking-related disease at the age of 78, and didn't regret a minute of it because he was an actual adult and lived his life as he chose and knew the mortality rate was 100% for all of us.
He lived a full, neurosis-free life; and he spent most of it running full throttle from people like you.
He was right.
Go ahead and smoke! I am not saying you cant! Someone wants to put a gun to their head and pull the trigger, fine! But dont put yourself where the it has ME in your line of fire when it passes thru your skull. Get it?
