A buddy of mine in college had an interesting theory:
He believed that the amount of sleep his body needed could be calculated not as eight hours of sleep per night but as 240 hours of sleep per month. Thus, he could stay up for three straight days so long as he fell asleep for the following 24 hours.
Unfortunately, his body didn't always understand the flexible deadlines. And sometimes he would get so tired that he would fall asleep while sitting up and talking. Literally.
Anyway, here was his interesting theory: A person can't fall asleep if he's wearing uncomfortable clothing. So on the days and nights he wasn't sleeping, he wore suits. To class. To breakfast in the cafeteria. To the dorm lounge. Everywhere.
Last week, I put the theory to the test. In the middle of a spell in which I hadn't eaten or slept for a couple days due to illness, I had plans to go out. So I put on a suit and tried to stay alert.
I'm smiling in the pictures, but it didn't last very long.
