I have been hesitant to post this person as a topic here, due to the fact that some people think he is a quack (not anyone here, necessarily, at least that I'm aware of), but I think he is a great doctor, interested in peoples' well-being, educating them about dangers to their health, and a person knowledgeable about both western and alternative medicine, with a bias towards neither.
I think he is an Idealist, but I can't exactly pinpoint which type. I want to say healer, most likely...he advocate a certain lifestyle to help people improve their well-being...he uses education though too. One thing I really respect about the man is that he is accessible...he explains his reasons for his conclusions, he doesn't talk down to his audience...He respects a person's ability to think for him/herself.
He doesn't seem like a promoter to me, which is something I had pondered at one time...is he promoting a certain lifestyle? It doesn't seem like it. He informs...he doesn't seem to have a schpeil.
Thoughts? Feelings? Reactions?
