I agree with what everyone's said here. There are many variables besides the human factor, such as the mercury mixture, your body pH, your eating habits, etc., etc.

I would also add, however, that mercury does not NOT affect anybody.

Mercury, wherever it is, follows the same chemical and physical laws, no matter who the person is. So, even though a person may be a better excreter of mercury, there is some degreee of exposure they do experience, and for many—including perhaps the nurse you spoke to—symptoms may include more emotional factors or I.Q. factors and other factors that affect things that people like them (the nurse) assumes are just a part of their personality.

For example, I was shy, had numerous fears, could not make commitments, didn't trust myself, had low self esteem, etc., etc. and never realized that ALL of these things were caused by mercury.

These problems are now GONE and I never even knew they were "problems". Perhaps the nurse does not either.

I'd be willing to bet that if she was questioned about "small" health issues that she has in her life, we would find numerous things that:

(1) are caused by mercury, and

(2) will become much worse as time goes on.

As a very physically active person, I had NO serious physical symptoms until just a few years before my removal. I was "very healthy", as far as I knew.
