As I finish off my residency, I realize that no matter how awful some of the remaining hours and the minutes can be, this experience is finite and bounded. My senior resident on my very first in-patient intern month took a sardonic aphorism from the seminal medical novel "The House of God" and added a hopeful corollary which has become something of an unspoken mantra. "They can always hurt you more, but they can't stop the clock."
