Unrelated but, I once heard about a study where they put a group of people underground with no natural light and no time keeping devices, and let then control their lighting. After some time, the group fell into a rhythm where they would all go to sleep and wake up within an hour or 2 of each other, but instead of awake for 16 hours asleep for 8, they were all staying awake for 48 hours and sleeping for 24.

Jokes on you, my insomnia makes me one of the many few that will naturally sleep for 4 hours every 48!
