Sorry about your "bad gene" there. I, too, had cancer twice in my life. Two major surgery's. Teams of Doctors both times.
Each time, they ask me if I smoked, and how much. I told them. Each time each team told me that smoking did NOT cause my cancers.
I am really sorry for you plight, but you know........some get it and most don't!
I understand your bitterness........but please..don't try to change the whole world. Please........
Life is a roulette wheel. Many people I knew never smoked and they still died. At least your still alive.
Everyone dies. ?????
Well, stealing oxygen anyway.
