I will not read the research, maybe that means I have my head in the sand (I am ok with that, so long as I can come up for puffs).
I already know through common sense and historical evidence that smoke inhalation is bad for your innards, and that nicotine holds very addictive properties. I use tobacco the same way I treat alcohol, bacon and ice cream...with moderation! (I do allow myself one proper hangover annually).
Reading and analysing statistics will encourage unnecessary stress for me. I read 'Life Is So Good' by George Dawson, the 101 year old man who learnt to read at 99, then co wrote his biography. In the book George talks about how in interviews people always want to know what his secret to longevity is, his diets and lifestyle choices. He made a point of saying he just ate what he wanted, when he wanted and he believed that his lack of knowledge and stress around the whole issue was actually what kept him healthy after all. "you folks are always stressing about what to eat or not eat, and that stress is killing you" (my hazy memory quote). George was not a smoker but I see the same kind of logic appears to be applied by that old fellow Richard Overton that liked his 12 cigars every day and lived to 112. National geographic have a little clip, but it is a little dated, he was only 109 at the time.
