I see these same patterns ! My step father and father didnt smoke they are both dead from cancer treatment! My mother smokes a pack a day and shes still kickin and she was older them both of them! a friend of mine quit smoking a year later he contrracted testicle cancer i believe from substituting candy and sports drinks, an old farmer I knew was healthy but old ,his family put him in a nursing home took away his pipe and daily quart of beer, he died in a month! Nicotine is an anti stimulous it takes the edge of of life, its calming affects might overshadow its so called damaging affects! Who knows I could be out in right field with this but I am tired fo being admonished for my use of it and refuse to be put in a closet or out in the hall or let people treat me as a second class citizen because of it!
