Friday Bed Magnet

It must have been a long and tiring week throughout our school, because there was a good inter-disciplinary crowd at happy hour this afternoon and we talked a lot about sleep -- how much people sleep . . . some people don't sleep much!-- for how long people sleep, what time they go to bed, what time they wake up . . . and all I can say is that I need sleep and writing this sentence is making me sleepy.
