Mysterious yawns: I wish that I could tell you exactly why we yawn. For all the research that has been done on this simple little activity, we really don't have a great idea why we do it. You are probably not lacking anything at all. We yawn in the womb. We yawn when we are tired. Sometimes we yawn when we are aroused or excited. I would not worry about it too much. Enjoy it. Yawns can feel great.
