my ancestors are from spain with a little bit of mescelero apache on my dads side , wanted to see if ancestory and geography plays a big role in mercury poisoning I know that native inuits in alaska gain 80 % of there food from the sea and local rivers ? my mercury poisoning is from amalgams without question ,my grandmother on my moms side lived to 96 years and had no amalgams ,the rest of my grandparents died early ages due to there smoking habits ,both my parents have many amalgams between them and have many different illnesses which could be linked to amalgams , they both do not drink or smoke and live a very clean life style
