I see many posts of people who quit smoking 15 years ago or more but end up with copd and/or lung cancer. It really makes me wonder why I quit. I gained 20 lbs, ( I’ve never been overweight before) and still can’t breathe outside in the summer- heat and humidity kill me. It gets better now in the fall. I really hate being fat; if I’m sick or soon to be sicker, why bother with the smoking?
