I just read this very interesting book called the Survival of the Sickest by Dr Sharon Moalam. Apparently, there's this hereditary condition called hemochromatosis, which is a disorder that causes iron to built up in the body, so much so that it damages organs like the pancreas and the liver. Liver overload.
Women don't have it severe because they menstruate. Men can treat this problem though blood donations or in the ancient times, they blood let. Apparently, according to the book, more than 30% of European descendants have this genes. Most men are not aware of this problem, and they keep popping medicine to deal with their disease instead of getting to the root of the problem.
Thought it would be interesting to pass this info on. If you think you and your family have this iron overload, do get tested.
