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.

My dad and I are kind of estranged, we haven't spoken in a year. So my mom decides it would be a good idea to let him message me. He texted me while I was at school and now I have no idea what to do. All he said was 'Hi _, how is school?'. Do I reply? Do I not? If I do, what do I say? My mom and grandparents are no help, they just cracked jokes about it. KidzWorld has helped me with a hell lot of things, I better not be let down this time.

Just act like you were introducing him as one of your friends. Be yourself, wear stuff that’s comfortable. It’s okay to be nervous because everyone will be. Just hang out and have fun.

one day I was eating lunch with my friends and two boys, (I'm a girl). when one boy told his friend and some other people, everyone but me who he had a crush on. At the end of lunch someone told me and it was me, later on he confirmed it and his friend told us he was on the verge of tears because I found out. people were telling everyone he liked me. Earlier I told him I liked him as not to make him feel bad, he told his friend who told everyone. soon rumors were started my best friend and his had teamed up to make an unstoppable rumor making and spreading team.  on monday it was our all day field trip and he needed to tell me something so on the way back we sat together across from his friend. She asked him if he still liked me. I covered my eyes but could still see and he was saying no but nodding his head. I told him to just tell me and he said yes. By then the rumors were getting really bad so in order to stop them we started hanging out, and became best friends. its summer now and we text each other all the time but we are just friends the rumors have blown over but now another has become true. through all of this,  I really like him now. I don't know I f he still likes me but I know that I really want him too because I really like him now! What do I do? Please help me! I'm so lost! this is all like a nightmare! what if it starts again. What do I do!
