Allegedly Dave is a rabbit hole digger in many, many areas. His book, The Human Body - Owner's Workshop Manual is an excellent guide that breaks the traditional health myths and replacing them health solutions. For an example of "new", which is actually old, is the true need and reason for fasting, why we should only drink distilled water and the 5,000 year old medicine of urine therapy. His life's mission is to dig into rabbit holes and help people with their lives. I've heard a couple of interviews and he's a very likable, humble, down-to-earth kinda guy. I think he would be a great guest and could offer some new information and enlightenment on many things, especially the human body aspect.
