The truth is I smoked for 30 years and did not realize how offensive the smoke was I was emitting and how much it bothered others especially people with allergies until I quit. Besides when I was at the state fair and took my grandkids to the fair to ride the rides and get some eats I often experienced people with lit cigarettes who "almost" walked into one of the kids . On the flip side, I know a lot of smokers who would not smoke at the fair. The good news is that no matter what age a smoker is the health benefits of quitting smoking are almost immediate and as the years go by get only better. The money ones saves by quitting smoking is a lot not including the money one saves on doctor bills and medicines.
