That's interesting. I note well down the article a mention of curcumin. It now seems that it's important, indeed vital, to consume the spice cooked with food.
My pal in Texas changed the path of his Parkinson's with taking curcumin but sadly having to take it in food wasn't known about then.
Back then, after some months of observation, I wrote a thread on here 'Have I witnessed a miracle?' (He had periods of being able to work again and even play the piano, though sadly not for long.) I also posted my pal's write-up which was in turn commented upon by Mac the Knife. Mac had found research being done just a few miles away from my pal in Austin which my pal was unaware of. All years ago now and said pal was last seen making his way around his home on a substantial scooter.
I used to pop pills for sports injuries all too easily and also rinse my hands in all kinds of chemicals after DIYing cars. I breathed in paint thinners and consumed rubbish food by the tonne. All rather silly really as I used to run and swim and even weight-lift until nearly 60. I could fool folk with an apparent fitness and even fooled myself for a long time.
It seems bodies need taking care of right down to molecular level but I fear it'll be a long time before we live in science fiction style medical perfection. Perhaps the new detailed awareness of the inner workings of the cells that make up our human form will prod people into improving their environments, but somehow I think most people assume it won't happen to them. I did.
