Famous quotes containing the word medicine:
“I have noticed that doctors who fail in the practice of medicine have a tendency to seek one another’s company and aid in consultation. A doctor who cannot take out your appendix properly will recommend you to a doctor who will be unable to remove your tonsils with success.”
—Ernest Hemingway (1899–1961)
