Exactly. I never knew there was mercury in fillings til a few months ago & it instantly made sense with my random symptoms. They thought I had multiple sclerosis lol. Had a hair test and I'm full of mercury. The thing with mercury and heavy metals is some people have genes that make it near impossible for them to detox heavy metals, which is why vaccines with mercury in are a terrible idea. That's why we see some people are fine with a heavy load of heavy metals because they have a better detox system than others. The other people store heavy metals, which leads to disease & disorders, which leads to either death or a lot of money being made...
