I think in the not so distant future. We are going to look at this time like we look at romans and using lead in everything the same way we use aluminum in
Everything. Nano-particle aluminum is extremely neurotoxic. There is a massively growing body of medical evidence showing aluminum contributes to alziehmers, Parkinson's and other neuro-degenerative disorders. Aluminium is in everything from vaccines to deodorant. Supposedly through the gut we excrete aluminum no problem, I think this may actually be the route that sensitive individuals probably develop their build up from.

I have switched from using aluminum based deodorants since the arm pit has a rich supply of blood vessels and sweat glands. This makes it very easy for aluminum to be absorbed into the body and bypass the gut where it would be excreted.
