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.

A Few Cool Yawning Facts

  • The average yawn lasts about six seconds.
  • 55 percent of people will yawn within five minutes of seeing someone else yawn.
  • Blind people yawn more after hearing an audio tape of people yawning.
  • Reading about yawning will make you yawn.
  • Olympic athletes often yawn before competition.

Agreed. He was hiding for a reason, but noone except him knows what that is. It may have been good or bad. By telling the teacher you stopped anything bad from happening. Your grandfather was right too, but I think that telling the teacher was the right thing to do. Also, don't worry. I had an aunt who was very very close to me, but I was very small when she died and was actually laughing at those people crying their eyes out because I was little and didn't understand why they were crying so much. I didn't really feel anything right then. And now I reprimand myself for being such an idiot about it.

I've liked the same guy for six years. I decided this year to finally get it off my chest and tell him. It took a lot of courage, and I was gonna do it the day before graduation... Except, little did I know, he went on a trip that day and I never got the chance. I then got his ######## and built up the nerve to add him. He hasn't added me back yet, and it's been a week! I shouldn't be as stressed out as I am. I can't stop thinking about him, but I'm not gonna see him for two months. Help?
