If you spent a third of your life doing something, wouldn't you be able to explain why you were doing it? Of course you would!! As it turns out, we all do something for nearly a third of our lives and cannot truly explain why, sleep.
Yes we know that we need sleep because of how we feel when we don't get it. We also know that sleep is good for us because of the way it makes us feel when we finally tuck into the covers at night. We know sleep is good because sometimes just the thought of it can bring that nostalgic feeling of the night before.
This intrinsic knowledge of sleep is what drives the science and research of our slumber today. Even the experts admit that they do not have a good answer for why we need to sleep. They have measured brain waves and studied test subjects but there is still no widley accepted answer for sleep. Maybe our class will have a break-though this semester and finally be able to explain sleep to the world!
That's optimistic! I like the way you think. I honestly think it has something to do with God's care for his creation--mentally, physically, AND spiritually--but I'm going to let each of you make hypotheses as we move through the course.
