Have you ever noticed that when you yawn, everyone else around you will often time yawn as well? I always thought people just did it on purpose because they thought about yawning. It turns out it is a form of positive feedback. When someone sees you yawning, it creates the need to yawn in their body as well. Our bodies react to each other in different ways. I guess yawning is just a physical thing that gets positive feedback from other people just because it exists. It's kind of gross to see someone's whole mouth when they yawn. It is interesting that our bodies copy each other like that.
