Not to be argumentative, but I wish to bring to your attention my experience with mercury.
As a teen, I would play with the mercury from switches and tear apart mercury batteries so common at the time for their droplets of the liquid metal. As a kid, had countless amalgams. At age 30 had teeth removed. At age 55, was feeling tired all the time so knew it was useless to see a MD and went to chelation MD. A lot of talk radio at the time discussed the benefits, so worth a try. Through muscle testing, it was determined mercury was the first to be eliminated by the suggested monthly DMPS IV chelation. EDTA followed months latter. Within 2-3 months I was feeling the benefits. Best $2K ever spent. Yes, I was part of the Hostess Twinkie /Coca Cola generation, hence was not on a healthy lifestyle like you follow and encourage here. So the bottom line is, I was convinced the metal was in me for an awful long time and hard to convince me otherwise. What other conclusion can it be?
