He's a think-outside-the-box doctor, who has helped so many people. Although he is courageous, it seems to me that his experiments - e.g. the snake venom - have been undertaken judiciously. I think he is far from cranky, rather a rare voice of reason who does not advocate taking a drug as a first resort. Also, I do not think he advocates 800 calories/day for life, rather for three days a week and there is so much evidence pointing to the benefits of intermittent fasting, which is, after all, natural to humans (I say this because we evolved from hunter-gatherers who could not rely on three meals a day). He must have done Big Pharma out of billions, tho' - could that...possibly...have something to do with his disappearance? I fervently hope he's soon found, but meanwhile I'll go and get my tin hat! :-))
