That is just exactly right. All the more reason to live and let live.
My ex was having chest pains at 38 years old. In the ER they did all kinds of tests. They walked in saying, "well the good news is you are not a smoker." Little did they know he had been a smoker since he was 13 or so and was at that time up to 2-3 packs per day, and was quite of smoker of other things for 15 years as well. (before I ever met him)
This subject just gets me so angry. There is just soooo much more to it than the "real or imagined" health issues.
