ORIGINAL: DomImus sorta like the equivalent of the massive doses of saccharine that researchers gave all those rodents years ago to "prove" that saccharine was a carcinogen. The same kind of thing was done with chimpanzees and cigarettes though. quote:
ORIGINAL: DomKen I thought you were asking rhetorical questions but your later posts show that you weren't so I'll explain it. First there has always been an explanation of why some people get cancer and some do not. A carcinogen is more properly called a mutagen. It is a chemical that causes unpredicatble changes in the DNA or RNA of a cell. Sometimes those changes kill the cell in question. Sometimes the changes don't do anything at all. Sometimes, very rarely, the mutation creates a cell that no longer stops multiplying when it should which is what cancer is. The odds against any single exposure to a mutagen causing cancer varies tremondously but it tends to be very low. However the mutagens in tobacco are repeatedly exposed to the same groups of cells over and over again which over the years greatly increases the odds but it is certainly possible to smoke 2 packs a day for life and never get cancer just don't count on it. I do appreciate the explanation, really I do. I don't smoke 2 packs a day, but I have smoked for a very long time (more than 30 years) and as I mentioned, cancer is one of the health problems I DON'T have. It doesn't mean that I have no intention of quitting at some point, nor does it mean I don't believe that cigarettes can cause various health problems. I do believe that some people are more predisposed to cancer than others, but I won't even say I have scientific evidence to back up that belief, because science gal just ain't me. Granted, the concept that cigarettes cause cancer has been consistant and unchanging, but so many other things are dangerous or not dangerous from day to day. Eat eggs, don't eat eggs, ok, you can eat them. Red meat is bad, red meat is good, no wait, it might be bad. Honestly, the way I figure it is that I want to enjoy my life while I'm here. If someone wants to live to be 100, and they avoid everything that they are told is bad for them, exercise like a maniac, etc., good for them. I would rather know that I had enjoyed my life while I lived it. Right now, that means I'm not going to quit smoking, I'm not giving up red meat, I drink alcoholic beverages, I swear, I have sex, I eat eggs. As long as those things are legal for me to do, I will enjoy my freedom to make those choices.
