Seems mysterious. I thought it could a number of reasons why. 1. Could be he wants to keep a low profile. 2. could be he had been ill for some time.....I disagree with not eating any protein...he looked emaciated. Human are omivorous not herbivorous and he was in fact kind of obsessed with not eating protein atall which is really in a way neurotic. He was a neurotic type but at the same time he had a lot of useful info about liver function. I took what I wanted from him and left out that I didnt agree with and that's ok,people should be free to say what they want and we take it or leave it.
3. He received death threats.???
