Why We Yawn

Yawning doesn't just mean you're tired.
Yawning

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 perfect friend according to me should always be there for you whenever you need him or her. But they should also guide you to the right path. They should understand you. They should be sweet, understanding, caring and funny. And yes, by caring and understanding I did mean a bff and not a boyfriend. My perfect friend posted on this thread right before me... her username is scarlet177.

I Feel like I should paste this here  Always remember this: Someone out there loves you. May be here online or on the other side of the world but they would care that you died. Now please put down that knife/blade or rope or gun or anything and think "do you want things to get better" or "do you want the chance of things getting better to be eliminated. Now let your scars fade and remember these words "I care"
