I avoid doctors in general. I schedule and keep appointments for my annual labwork (blood) and checkups. But as long as those are OK (so far), I don't see him for anything else.
I'm very aware of my body, having lived in it for 65+ years, in a wide variety of circumstances.
I hope that a doctor can provide some overview expertise. I know about *my* body but she's seen all kinds of people with all kinds of problems and knows about things I've never thought of.
Though I don't know if this system where doctors have 100s of people and when they don't always see us enough to get to know us really helps doctors gain that kind of expert knowledge as well as it might have in the past.
