Why We Yawn

Next time you're with a group of your friends, try this out. Take a big yawn, don't forget to cover your mouth, and wait to see how many other people yawn. There's a good chance your yawn will be contagious. In fact, before you even finish reading this story it is likely that you'll yawn at least once. Not that I'm trying to bore you, but just reading about yawning will make you yawn.

Yawning doesn't always mean you are bored. Adelie penguins actually yawn as part of their wooing ritual. Couples face each other and the males stand with their beaks wide open and face towards the sky.

As for why people yawn... good question. Nobody really knows why we yawn. For a while scientists believed that you yawned when there was too much carbon dioxide and not enough oxygen in your blood. Part of your brain realized this and triggered you to yawn. As your mouth stretches you inhale deeply, sending a shot of oxygen to the lungs and into the bloodstream. That theory went out the window because nobody can prove it.

The reason yawns are contagious? Power of suggestion perhaps. If you're out late with your friends after school, you're probably tired. You're probably on the verge of a yawn, too, and seeing one person do it is enough to drive everyone to yawns.

Have I made you yawn yet? If I have, I hope it's not cuz you're bored, but simply by the power of suggestion.

If you really want to get rid of the romantic feelings for him, just try picturing a future with him, and also asking these questions in your head, "Is he a good guy?" "Would we last?" But maybe he's acting awkward around you, because your friend asked him to Prom, but he might rather go with you, but doesn't know how to say anything about the situation. I would suggest talking to him about it, and if he is a jerk about it, don't bother. But talk to him first, and if he has the same feelings, then talk to your friend about it. I just want to warn you, that if you do this, you and others could get their feelings hurt. Crushes are a risky, scary thing in high school. Anyway, that's what I think you should do. If you don't want to do that, then follow what your intuition tells you.
