The de facto trust in doctors as the "experts" is THE BIGGEST PROBLEM in personal health responsibility and effective preventative medicine today. Most physicians are completely brainwashed by the BS they are fed whether in schooling or in the subsequent propaganda they get from the pharma industry. (This is also driven further through the massive kickbacks they get for vaccinating their patients.) Subsequently their patients are brainwashed by the BS their physicians spew as a result. It's a case of the blind leading the blind, yet believing that they can see 20/20 thanks to the pharma-led "research" they have received at the top of the pyramid.
Then on top of it you have these ridiculous TV doctors like Dr. Oz that are sent out to further manipulate the populace through the idiot box. Dr. Oz and his ilk have been created to influence a populace that is slowly starting to realize how bad the allopathic medicine system really is. Check out these two videos on the BS of Dr. Oz (in case it isn't already apparent.)
