“What I remember about the hospital—what I guess everyone remembers—is the smell of the disinfectant and the sound of the machines. Mostly the machines. The way they beep. The only other stuff that sounds like that is the equipment in airplane cockpits. I asked a pilot once, and he said the navigational gear makes that sound. I remember thinking that night that there must be a hell of a lot of navigating going on in hospital ICUs.
