On a somewhat-related tangent, I have a friend who swears by someone who is a self-taught doctor / nurse-practioner. This "doctor" cannot prescribe medicine obviously but is able to do checkups, etc. with self-purchased equipment and interprets OTC blood tests on his own. He apparently knows his limits and has sent people to the hospital when a situation exceeded his knowledge. He is completely self-taught from material online and books from the library
