i think humans have not adapted to be functional at night. We've evolved to be able to make the choice of whan we want to get up or go to bed. i wonder if that means it people say in new york, where they have more open late options, tend to have a different sleep cycle then people. And say, sedona, which i visited, and their late night eating options are shit. I ate fruit salad from circle k after a wedding sucked sedona on blast.
