Yeah, seriously! Besides my own personal productivity, I also noticed in college that the amount of sleep my dormmates got correlated well with academic success, moreso than class attendance did. Of course it could be that those who struggled just had to stay up later, but I'm pretty convinced there was a terrible feedback loop in play.
