Before everyone goes on about college life, the study was done on elementary and middle school students. Not to say that college life and university students aren't sleep deprived. But I feel like the exact result being reported here is even more worrisome. This isn't going sleep deprived while you're (hopefully) adding the academic final touches to your more or less developed brain, this is going sleep deprived while your brain is still coming together.

While the article tries to end on a happy note ("Don't worry! There won't be any permanent damage... if there hasn't been any permanent damage"), I feel that it's still worrisome.
