One thing missing from ANY discussion about aluminum in connection with Altzheimer's is the way aluminum adversely reacts with MERCURY in the environment. At the risk of starting another conspiracy theory, anywhere and everywhere you see blackened and / or pitted aluminum structures outdoors (unpainted aluminum, obviously), it got that way through the action of aerosol mercury from coal fired electric power generating facilities. The chemical reaction between the two is a rather violent means of corrosion, and the two elements tend not to separate easily after they have reacted. After which, the occurrence of bonded mercury is everywhere humans habitate, and becomes something much more toxic than the ubiquitous presence of lead paint of another era. It is hard to believe that with all the recycled aluminum cans we use, some of that mercury isn't getting into someone's cans of Red Bull. You see how simple it is to start another conspiracy theory, Eugene? How much research have I really done? Let someone else monitor the mercury levels in aluminum. I have neither the time, nor the resources, besides which, I'm as mad as a hatter from mercury poisoning. It wasn't because of thymerosol, either.
