I have heard about this and--oy!--this is not good news for me. As a child, I had numerous mercury fillings. My mother, like most suburban moms of her generation, bought a lot of canned goods when they were made of tin!
Then, there were metals in the drinking water. I brushed my teeth and slathered on deodorant for nearly five decades.
Not only was I exposed to all those heavy metals, but I went through years and years of sleep deprivation and extreme levels of stress (life and death). Rampant and unchecked diabetes (high blood glucose).
And now, I am feeling the effects.
