My experience in aircraft maintenance has helped me realize something. not to degrade the profession since all have some merit, but something I've realized over the years is that doctors are people mechanics. it's impossible to keep up with all the medical research that's being done, and it unfortunately becomes a challenge to human pride when a patient comes in telling you that there's science their not privy to, so their reaction is often one of "I'm the doctor here" and blow you off mentally
