Yawwwnnnnn, its late. Hello to the new follower, yahhhh I have more followers. Thus, my ideas are a squid. Here is todays topic:
Why do we yawn?
Since its late, I'm going to do an easy question. I didn't have time to post earlier. Anyways, yawining is the flex of muscles such as the jaw for about six seconds. Beleive it or not, thereare only THEORIES as to why we yawn; if you asked this question your not alone. The most illogical reason is why yawn due to boredom. However, this doesn't explain why people from the olympics yawn before they perform. Another theory is that when we evolved, yawning was a way to start to say change the subject (super illogical, if you ak me). The best bet is that yawning takes in oxygen and takes out carbon dioxide. THis is why we yawn in groups. But why don't we yawn during exercise? I'll leave that for you to find out, as experts don't know.
Please comment.
