This is a huge presentation from GrassrootsHealth, much of it likely inaccessible to the average layman. So let me help. I could certainly use as much knowledge as possible -- and let me come clean about something. It's weird, at the age of 47, having completed one career and then started a successful company that pays my way even when I'm not there, only to find that I probably should have studied biochemistry instead of mathematics, computer science, and ultimately, business administration. I must have been derailed by my teenage infatuation with layman physics and pop cosmology, which set my course. I ultimately became unsatisfied with high-level math because, I dunno, I didn't smoke dope (at the time). It was just too inapplicable to the practical realities that interested me then. Biology was the farthest thing from my mind, and her I am, decades later, pouring over ever study I can get my computer on. Computer programming was cool, and it teaches you logic like nothing else, but I got impatient with the stone age way computer time was managed at the university I attended, and I just had to move on.
