There are twenty-four hours in a day. This is a fact of which every human - and especially every college student - is well aware. Unfortunately, it never seems as though twenty-four hours is completely enough for everything that needs to get done. It does not help that approximately (allegedly) eight of these hours are dedicated to being completely unconscious. Sleep is such an essential part of the human routine that many of our non-daylight hours are devoted to it. And yet, while we understand the rejuvenated feeling of a good night's sleep or the tired crabbiness of a pre-coffee early morning, no one seems to understand the actual purpose of sleep itself.
