Sorry to hear about your brother. I lost my brother to lung cancer at 45 in 2001. A dear friend of mine (we worked together from 1980 until she retired 12/31/04) just sent an email stating that a mass was found in both of her DH's lungs and the doctor is pretty sure that it is cancerous. He is 63 and has smoked since he was 13 yrs old. My 28 yr old son states that he smokes socially. I can't believe that he smokes at all.
I smoked from 1971 until the end of 1985. I can't believe that I was ever that stupid! It is hard to quit and I personally think that quitting cold turkey is best. My DH went through a program at WVU for approx 1 yr with meds and quit, then started again and finally quit again without meds this time. I hope and pray that he does not start again. He has gained so much weight though, which I worry about from the health standpoint. I keep wondering if I could have a slow growing tumor growing in my lungs, that has not caused a problem yet. I would like to get tested, but I don't think insurance would cover it and it would be expensive.
We toured the USS Bowfin when we were in Hawaii and I don't think that I could hack the submarine life. I know very little about submarines, but maybe they are bigger now. I still could not do it.
