I was once thrown out of a mental hospital for depressing the other patients.
The best doctor in the world is the veterinarian. He can't ask his patients what is the matter-he's got to just know.
Basically, all women are nurturers and healers, and all men are mental patients to varying degrees.
To study the phenomenon of disease without books is to sail an uncharted sea, while to study books without patients is not to go to sea at all.
