Why do people always say that doctors can't find a partner?

Male doctors are easier to find than female doctors, but women will think that people who can get a doctorate are either nerds or machines. When they hear that you are a doctor, they will think that you are rigid, so they are too lazy to go out and have a try. And the female doctor, the third kind of person, you know, the bachelor's and master's degrees are all ruined, and the male doctor can only protect himself. Women are too smart and too bad for men. .
