Guys, I've been noticing that when left to my own devices, that I'd rather be awake around 18-20 or so hours, then sleep around 10... Obviously this doesn't work around that thing we all call The Sun...
Fun part is that I suspect that it'd go closer to 24/12 given time... Back when I was a youngster/hacker, and had some time off, that's basically what I was doing... I'd get all over a problem, crash, wake up, get back on it... and the physical time didn't mean much.
Any ideas?
