Look. It's hard enough to get to three score years and ten anyway, what with all the things that could go wrong with the human body. So why on earth do hundreds of millions of people across the world continue to pollute the innards of their body with nicotine, tar and other chemicals, when every single packet of cigarettes they buy has HUGE WARNINGS (yes, like that) telling them they're seriously damaging their health and could die as a result? Addiction? Sure, but we're not talking heroin here, we're talking about a little will power and the desire to change one's life for the better. And they'd save themselves a fortune into the bargain, what with the current price of 'smokes'. Cancer isn't a disease that can be caught, it's simply the natural cell reproductive process starting to go horribly wrong. And the presence of cigarrette smoke and chemicals is a damn good way to start that sort of mutation off. Continuing to smoke is suicide. Literally.
