superficially, that SEEMS like a valid point, but is actually false and misleading. first, the avg human life SPAN is 140, as determined by our genes. always has been. what you're referring to is avg life EXPECTANCY. whole different animal. when lots of young men die in wars, die in coal mines, die in farm accidents, die doing ball-busting manual labor, die of infectious diseases, it brings avg life EXPECTANCY way down. BUT, there have always been plenty of centenarians. so the argument that NO ONE lived long enough to develop cancer is BOGUS. a far more plausible reason to account for the comparative absence of cancer before the civil war is the deluge of carcinogenic synthetic chemicals that have been dumped into the environment, the water supplies, the food supply, the very air we breath.
