I have a staff planning meeting in a couple of minutes. It's too short of time to get any work done, so I'll just make a quick post.
Have you ever wondered why we yawn? Scientist evidently do. There are findings coming out about the reason or function for our yawnings. According to this article, yawns occur to cool our brains down. Which means yawning is like the little fan on the back of the computer keeping the motherboard cool. Our brains, like computers, work better when they are cool. Which explains why breathing through your nose when you are tired can reduce your yawning...you've just brough cool air near your brain, cooling it off.
Sure, kinda random. But it's Wednesday and I'm in need of some randomness!
