If you wear a tin foil hat, you are more likely to have Alzheimer's. "Tin" foil is really aluminum foil. Also, "Alzheimer's" contains the chemical symbol for aluminum, Al.
Seriously, I thought the Al->Alzheimer's link had been discredited. The amyloid plaques just seem to trap metals, I thought; the plaques are the real problem.
It has not been discredited. It's just no one wants to endure the wrath of the milti-billion dollar aluminum industry by declaring it as the cause.
All victims have aluminum deposits in their brains. If amyloid plaques trap metals, why is it that only aluminum is trapped? What about iron? The body is loaded with it.
