Going to the doctor is like going to the car mechanic. It falls right between “trip to DMV” and “post office during the holidays” on the list of errands that we all hate doing. Just like the car mechanic, it can be expensive and even if they don’t fix the problem, you still have to pay. When they do find something wrong, you have to take their word for it and assume that whatever course of treatment they suggest is best. If you try to go against their recommendation they give a condescending stare and then ominously warn, “OK, it’s your life do whatever you want, but it really isn’t safe.”
But at least some people know something about cars that can give some advice. We all have a friend who spends the weekend with their buddies fixing cars. I don’t know anyone who sits around on a Sunday with friends working on each other’s hypertension.
