MIT Students were a hard-
partying studying bunch. That meant the number of hours devoted to sleep every night ranged anywhere from 6 to zero, and like Elvis, many of us wished that there were more than 24 hours in a day. Every so often, lack of sleep would catch up with a student. It's just that the timing could not be predicted. Fortunately, MIT had sofas. And the sofa in the common area of our dorm floor was just comfortable enough to snooze on.
MIT also had nice cushioning on the chairs in the Student Center library, which tended to encourage certain responses that were unintended.
It wasn't just humans whose sleep patterns got thrown out of whack.
