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.

Next time she tells you, see if you can find any evidence that she did, bruise etc.  even if you find nothing that doesn't mean she hasn't. But she or you should tell an adult, or someone you can trust that is older.

I have had problems remembering what we did the day before is certain classes. HELP ME!  At first, I thought it sounded like ADD, but it wouldn't effect your memory like it is. If not, catch your mom while she's not rushing around. Maybe before she goes to bed or while she's making dinner. Maybe even while she's sitting down or send her a text for her to see when she can. I wish the best of luck with the stress! It most likely doesn't help with the APD; stress can add to just about any condition!
