I'm hesitant to get a personal doctor because they all feel like they know it all and that is a dangerous attitude to have.
It's society's fault for elevating them to such a position and making them feel like they are the final authority on health. When in reality they still don't know how many things in the body work. A lot of things remain a mystery to them but they wont admit it. They must continue to give the patient/client the illusion that they know it all.
