The story is wrong!
Duke DID eliminate 8 am classes, they now begin at 8:30.
But it wasn't b/c of sleep deprivation!

It's funny; I saw the information about this on CNN as I was sitting in my dorm room, thinking, "they're wrong!" I go to Duke and unfortunately, sleep deprivation was NOT on the tip of the administrators' tongues.
