College is all about finding yourself.  Finding out how much money you can spend on random crap you don't need before running out of money.  Finding out how much you can drink before having a night stuck face-in-toilet.  Finding out how many girls you can sleep with before you catch something.  But most of all, how much sleep you actually need.  Or at least how much one can survive on while still being able to respond when the teacher calls on you.

Sleep: 1 Osaka: 0

After one of my finals, specifically for my dreaded 8 am class, my teacher took me outside and said something along the lines of how I'd slept through most of her class.  Whatever, I wasn't really listening, I just wanted to go back to my bed.  She asked if I had work during the night time which would have kept me up, which is sort of true, depending on what you call "work."  Dealing with roommates who won't shut up is, in fact, hard work. 

Most of the time I went to bed around 12, and although I'm not any good at math, is less than a full night's sleep if you plan to be productive the next day.  But we've already seen how productive I can be, haven't we? 

There's nights, such as ones after the midnight release of Call of Duty Modern Warfare 3, where you don't really want to sleep.  At that point there is balance that needs to be maintained.  The balance between how much you can get accomplished that night versus the amount of caffeine it will take to last you until you can come home and crash after your classes are over with.  Then there is always the worry you will become nocturnal permanently, which doesn't bode well for any social life one would have during the daylight hours.
