Listen to his talks...they start out slow but wait through that part. He's fascinating!
He speaks at the AcreUSA conference every year so I've heard him a couple of times. I also sat in on his question and answer time.....he always always comes back to Iodine as the fundamental mineral that ties all else together.
I'll go through my notes later tonight and see if there's some other interesting stuff he's said. He also emphasises selenium.
