I noticed in your note that you think autism is related to metal poisoning... later on in your note you mentioned that you give Colloidal Silver to your child. I know that Colloidal Silver has a good rap whereas mercury has a bad rap.... in the 1700's i believe that mercury was given to people as an antimicrobial agent -- i'm not so sure that giving silver to cure an ailment isn't the same sort of thing.
i know there are alot of proponents of Colloidal Silver , and that these people believe the body excretes the silver soon after ingestion. i personally don't believe that is so.
