" There’s long spells — three days, years — when you can’t see a thing, know where you are only by the speaker sounding overhead like a bell buoy clanging in the fog. When I can see, the guys are usually moving around as unconcerned as though they didn’t notice so much as a mist in the air. I believe the fog affects their memory some way it doesn’t affect mine. "

― Ken Kesey , One Flew Over the Cuckoo's Nest
