In college, I stayed up at least once for 40 hours straight (though I think I did this a couple of times). I had to do this to finish my last assignment at college. I woke up at 8am the first day and typed nonstop except for when I went to lunch and dinner for 23 hours. I wrote 30,000 words in that time for my final assignment. After that was done, I went to the cafeteria to eat, went to the library to print off all 140ish pages (I was lucky there was enough paper/ink/etc), and then went back to the dorm to work on my tri-fold poster board for the rest of the assignment. This took me a few hours to complete. I then practiced my presentation I was going to give over this assignment, which was about my student teaching experience. I played some Just Cause 2 for the couple of hours before the presentation, and then went and presented my thing over and over again for different people for about 4 hours straight. I was going to go back home and immediately sleep, but my fellow student teachers made me go out to eat with them. When I got back, I wasn't feeling so tired anymore and stayed up a few hours doing silly stuff with the roommates. All in all, it wasn't a horrible day.
