I use to think it funny that surgeons insist (well not so much now) on being called Mr. instead of Dr.. Why go to the bother of doing medicine and then another exam afterwards just to go back to being called what you use to be called before you did all these exams.
Well that was before I knew how much they earned.
It used to be the case that surgeons weren't doctors; they were usually butchers or barbers.
I'm not sure if they earn much but they do get paid big money.
