He's interesting, but I strongly suspect he's had some kind of training in manipulation. I'm not saying he's wrong - especially on what he says about sunlight being good for fighting cancer - that feels right, but my Spidey Sense goes off nonetheless. To summarize the training I think he's received : there's a trick that scammers use to isolate victims while speaking to a crowd (it has a name, but I forgot it), which is that you start off reasonable and affable, but slowly add in details that wouldn't have sounded reasonable when you started. As you keep doing this, the smarter people drift off and the stupid people self select for you. Or him, not you. English... Anyways. Worth checking out, but be prepared.
