Quote from : Infinite Jest Book

Doctors tend to enter the arenas of their profession's practice with a brisk good cheer that they have to then stop and try to mute a bit when the arena they're entering is a hospital's fifth floor, a psych ward, where brisk good cheer would amount to a kind of gloating. This is why doctors on psych wards so often wear a vaguely fake frown of puzzled concentration, if and when you see them in fifth-floor halls. And this is why a hospital M.D.--who's usually hale and pink-cheeked and poreless, and who almost always smells unusually clean and good--approaches any psych patient under this care with a professional manner somewhere between bland and deep, a distant but sincere concern that's divided evenly between the patient's subjective discomfort and the hard facts of the case.
