Not sure if you have seen this site but I found it extremelly interesting.

I didn't look over the whole site, but saved it to go look back on... I've got to get ready in a few minutes... but I will say this...I do agree that mercury and othe rmetals are bad for your body.... and even iron in EXCESS can be bad.... HOWEVER.... your body needs iron and other minerals for it's brain. Being anemic is very serious...*smiles* I know, I suffer from it. If I don't take my iron pills I'm fatiqued and useless to anyone and I bruise easily... sometimes just from someone touching me. This is what is hard about things... have to becareful of what you buy into cause people become fantatical and suddenly you can't do anything at all without harming yourself, your child, and other loved ones... it's rediculous. I'll still look over the site though... some of it looked interesting, if for nothing else, the information... LOL... I love learning about new things. The part I think is interesting is the traits of autism that Dr.s don't see but when you ask parents they all had them in common.
