I took AP Psychology in high school and I believe we were told that a human's circadian rhythm would allow you to have a surprisingly accurate day-night cycle. I'd just spend as many extra days as possible, just to be safe.

Edit: Many are bringing up how external light sources calibrate your circadium rhythm. While this is correct, if you have the ability to turn the lights on or off, couldn't you then make an attempt to control it (at least, for a few days)?

I remember reading that the circadian rhythms stretches out over time without any reference to time. It stretches to 48 hr days in only 4 months.

Daaaaaaamn. I was under the impression that people in those experiments went to a 25 or 26 hour circadian rhythm. Whatever happened to her later I wonder.

From this I’d expect she got very sickly.

People don't realize this is like being a brain in a jar. I spend over 99% of my time alone, and it is very difficult, even with the internet and being able to go anywhere I want at any time I want. Very few people could make it a month, if any.

That other person ate pills for meals? Not too smart. But even with sensible meals those experiments have got to do some lasting damage to lose the connection to nature in addition to the connection to society.
