Yeah, this is kind of what I figured. A person is exposed to so many things during a lifetime. Usually, you assume that brief low level exposures to toxic materials doesn't cause major damage. (You don't have any immediate symptoms of a problem, so you assume everything is fine.)

But the additive effect is hard to predict. It seems like every time I do a bit of reading, I find about 5 more things that could be causing me a problem. But no way to know which ones (if any) actually are causing me a problem.

So, I'll just continue to work towards healthy living, a healthy diet, and a range of supplements to support good circulation, healthy nerves, and mitochondrial support.
