" If it is a question of trepanning, I am your man. It is an operation I have performed scores, nay hundreds of times without losing a patient. That is to say except in a very few cases of vicious cachexy, where it was only done to please the relations. I trepanned Mrs Butcher for a persistent migraine, and she has never complained since. "
― Patrick O'Brian , The Far Side of the World (Aubrey & Maturin #10)
