Doctors are some of the most ignorant people there are.
Reason is they spent practically all their time from HS to Internship learning to be doctors at the exclusion of all else..................
We borrowed a vehicle from a doctor friend for a short time a few years back. It was during the winter, and the heater didn't work well. I discovered that someone had removed the thermostat. He thought you only needed that during the summer. Needless to say, I remedied the problem and the ignorance about the problem.
