Two things prompted this post. One, I have just received the movie by this name from Netflix. Two, I just read an article about the latest sleep study. Prepare yourself for a shock.

Anyone who has stayed up all night cramming knows that they would the drowsiness that ensues is more than a little counter productive. Oh sure, the procrastinator in us will keep doing it. But it seems fairly obvious that it's not the wisest of plans.
