On the subject of doctors who write

"So why do these doctors write so well, and so much better (to my mind, at least) than other non-writers? Perhaps there are elements of doctoring that lie in harmony with writing: peeling back the layers to get to the core of an issue; confronting the obvious but being willing to look beyond it; learning where to 'cut in,' of course; and, more than anything, recognizing that this object before you – in one case a human body, in the other a manuscript – is on a certain level a miraculous object with the power to astound, and on another level is a complex, dynamic system which can (and must be) reduced to a schematic, laid out on paper or x-ray film."
