An interesting aside...

A while back I stumbled across an article by a 'scientist' who suggested that it wasn't so much aluminium that caused Alzheimers, as a similar metal called berylinium (sp?).

He explained how the two metals are very difficult to place on the periodic table, and how the skin on the arms of unprotected workers with berylinium behaves much like the brain tissue seen in Alzheimer patients.

He concluded the article by asking that someone buy him a lab coat.
