I wonder if how quickly someone excretes mercury plays a part?

I'm no expert, but have come to the following conclusions on how someone is poisoned by amalgam (as not everyone gets sick from it - at least not severely).

1. Sensitive to mercury (maybe in varying degrees)

2. Slow or non-excreter of mercury (so builds up to toxic levels)

3. Sensitive AND slow-excreter

I've been thinking that (other factors aside) maybe those with the best chance of recovery are:

1. Sensitive to mercury, but fast excreter

Poorest chance of recovery

2. Sensitive to mercury and slow-non excreter

Just something that occurred to me.
