My seemingly endless medical school days of gleelessly skipping lectures and spending far too many hours on crosswords, of obsessive toast eating and long hostile runs after which I’d get into bed unsleepy at 8 p.m. simply hoping to bring the day to a close a little bit earlier — that would all be over soon, for a year at least.
