I believe the following are the primary culprits (over 50%) of the rise in disease?especially neurological?in the past 30 years (Demi has a more complete list):

- Lead in paint
- Mercury in amalgam fillings, vaccines, fungicides and paint
- Fluoride (hydrofluorosilicic acid) in water
- Arsenic in treated lumber
- Pesticides
- Preservatives
- Demineralized foods (via processing and pesticides)

Six are toxicity, one is malnutrition. It's all man-made (big surprise there).
