Why we laugh?

Did you know that you're 30 times more likely to laugh if you're with somebody else than if you're alone? Cognitive neuroscientist Sophie Scott shares this and other surprising facts about laughter in this fast-paced, action-packed and, yes, hilarious dash through the science of cracking up.By Sophie Scott.Whether it's the giggling of a child or the enthusiastic hollers of a talk show's studio audience, we hear laughter every day. Nothing could be more common. But just because it's common doesn't make laughter any less strange. For instance, the next time you're at the movies enjoying some comedy, listen hard to the laughter around you.  Once you start looking at laughter as behavior, it can lead to some odd questions. Why do we do it? Do animals laugh? And why do we expect that any decent James Bond villain will cackle diabolically when revealing his plan for world domination? What's so funny? "Most laughter is not in response to jokes or humor," says Robert R. Provine, a professor of psychology and neuroscience at the University of Maryland Baltimore County. Provine should know. He has conducted a number of studies of laughter and authored the book Laughter: a Scientific Investigation. One of his central arguments is that humor and laughter are not inseparable.In my case, I tend to laugh when I feel overwarmed by a situtation, when somebody looks at me deeply or when somebody falls (this is so awkward because I laught instead of help that person and they get angry) or even when I fall. I don't usually laugh with jokes or with comedy films, but when someone falls or uses a wity sense of humor I can crack up for hours. I remember one day when I met my boyfriend's mom, I was scared because I amb an extremely shy person and I don't like to meet new people, so going straight: we were having dinner and she looked so serious and I was red AF. So she was talking with my boyfriend and I was like... "ok, I don't like the dinner and they are ignoring me, what can I do?" I started to watch the tv and  it was APM, a catalan humor tv show and it showed a boy that was dancing (they were still talking without me!!!!) and that boy felt.What happened? Of course I started to crack up ALONE and when I laugh so hard, I do a pig noise and I snore. They where looking at me like WTF is wrong with you? And the more I got ashaim, themore I laught and I felt warm. I couln't stop. My boyfriend's mom started to laugh as well and she cracked up as well, since thet moment we got closer and then we started to talk.At the end it wasn't so bad to meet her.
This is my prove that laughter enhances relationships, you can hate or like a person with just a laughter attack. 
The reason why I laught? Mmm... I don't know but maybe it's because when I was a child and I fell, my mom smiled to me and do silly faces to feel better.

Graduation: Now what?

Hello! This is my 1st post in 2nd of bachillerat, which is a decisive year for our future. This year I am going to graduate from the high school and start to build my future. As you might know, the next step is to go to the university and do a carreer and that's terrifying for me! I mean, how I am going to know if what I am studying is right for me or not? Will I be good enough? Or will I have a job associated with what I've studied? Well, I hope that! I hope to achieve my goals and be strong enough to get my dream job and pass the job interviews.
Everybody tells me that I am too shy and that I have to be more shameless because in college or in a job I will have to do a lot of oral presentations, comunicate with other people and do this kind of things. One thing in particular that I have to improve is my body lenguage. Last Thursday I did an oral oresentation, I had a nice prezi, all memorized, everything was under control, well, almost everything: I was TERRIFYED! The teacher told me that everything was fine but I have to loose my unconfidence and my shyness, and that's why I have chosen this post from Ted.com. She's sor inspiring, she had a problem with her confidence when she was at college, and now she's a nice psicologist.
I let you the video bellow:

Your body lenguage shapes who you are. 

Body language affects how others see us, but it may also change how we see ourselves. Social psychologist Amy Cuddy shows how “power posing” — standing in a posture of confidence, even when we don’t feel confident — can affect testosterone and cortisol levels in the brain, and might even have an impact on our chances for success.
