Evidently, you don't know the difference between the element of risk, and a dangerous worksite. Then again...you don't have a job that has the same element of risk that the average factory worker, construction worker, lumberjack, or miner has, either. The jobs you mentioned are, by their nature, risky. Accidents happen in those places at a higher rate than second-hand smoke causes cancer, too. You want perfectly safe? Never leave your bed, and drink protein and vitamin shakes for meals. Until then, you need to think before you write that drivel, because you don't have the breadth of experience to argue me on this one.
