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.

Its my best friends birthday party on Friday and I still don't know what to get her. She's turning 12 and she loves: guardians of the galaxy and Shopping at Newlook. she wears jewellery quite likes hair and beauty products and enjoys watching movies, going to music concerts ( she likes Taylor Swift) and apple products. I'd rather not use gift cards because they're like the lazy option out and she's my Best friend but if you can think of a great brand for her then ok.

Talk to your parents about it. Tell them you didn't like your Christmas gift, and don't let your brother boss you around. Your parents can, your brother can't. Your parents gave you life, sorry to tell you but they can do anything they want if it's legal. But your brother can't. Let your parents know that you shouldn't have gotten in trouble for the stuff he doesn't. Tell them he makes you feel really awful and you don't like it. If they're good people they'll understand.

I would stop being friends with her. I mean she should understand that it'd be mean to do that. It's hard to help your friend get through a breakup when you're dating the same person. Plus you don't even know if she was trying to break you guys up so she could be with him.

You want to know if he likes you or not? Just ask him. It's not as bad as people say-I mean, it's a question. It looks like he does, so he probably does. It's not that big of a deal.
