I don't know if you were really ingesting the mercury by rollling it in your mouth. I had a vial of it too, as a kid, because my dad was a science teacher and brought it home. It was in the silvery form.
The problem with the mercury in the vaccines is that it is applied to babies whose immune systems and physical development is not at a level where they can withstand the effects. Just as when a baby is born, it does not look like a miniature adult, his/her internal development is not mature either. He is growing iside as well as outside, and high levels of mercury interferes with the proper development of important neuro-pathways, etc. There is a narrow window, as I understand it, when those pathways can be built and further development cannot take place until the neuropathways are in place. Some doctors point to the autistic's ubiquitous "sideways" glance (where the child never looks directly at you) as a symptom, for instance, that the rods and the cones in the eyes are not developed correctly.
The few autistics who have recovered tell of sort of a "tunnel vision" where the focus of their vision is off to the side. This is a problem that many adults have with autistics as they fuss at the child to "look at me" and the child is looking at them out of the corner of his eye -- which is the only spot he can see clearly.
My grandson had 4 times the acceptable levels of mercury in his system when he was tested, just from his baby shots.
Do you KNOW that was the source?
