That's very interesting, actually. I didn't know that. I only knew, that blacks in europe would need to take diuretics, because they can't get rid of the excess water in cold environments. So I'd expect them to be rather high on the ladder with organ-damage and vascular-disease. And cancer is caused by food-intake to a large degree, of course, but there also are genetic factors. Regardless, I'd still expect differing cancer-rates between whites, blacks, and mongrels in the long term, with mongrels having the highest rates, because of their scrambled genome. But that's just a theory which I hope I'll never know the truth about, because all africans are shipped back to africa, so nobody's genome gets scrambled...
