Fun! I think a lot of students find an optimal sleep pattern, just because they can (depending on schedule).<p>There was a year that I slept from around 3am to 9am, long-ish siesta in the early afternoon (1pm-4pm). It was the most productive time of my life, and I felt well rested. I really got a lot of work done in those late evenings&#x2F;early nights; Everything calmed down in the dorm, noise outside was lower. Morning was for chores&#x2F;part-time job.<p>I wish I could return to this. I&#x27;m more or less 9-5 now and always tired.
