Hey Diane. I'm starting to believe that everyone that has amalgams in their heads are affected in some way. It may not be noticeable to even themselves. Since we know that every time we chew vapors of this poison is entering into our bodies, some get flushed out immediately and others will find their journey into a hidden area in our body. I think looks are deceiving, I think that all those with amalgams are sick from one degree to another. For those who appear very healthy it many mean the poison has not caught up to them and may never catch up to them in their mortal existence. But I still think that their body is fighting the intruder in some way. I think sick is a very "relative" term.
