Interesting theory - that said, note how probably very few of these old people boxing look like they exercised more than walking around their house or work the last 30 years, no offense to anyone just saying...... Personal health comes from all angles!! UTL COMMENT:- I read a study once nearly ALL Parkinson's patients after death when tested had high levels of Aluminium in the brain.... So cut back on aluminium products! No more aluminium foil, no more canned drinks, no more cooking on aluminium fry pans!!
