Why are doctors so good at treating ill or sick people?

I find treating myself is hard and I’m around myself 24/7.

So no idea how a doctor can talk to 30 patients a day and heal them all in 15 minutes.

I had a church friend whose father was a doctor and I described my health issue using bizarre and unusual phrases to hide my situation and immediately his father knew what the problem was. The next week the doctor’s kid described my problem to me.
