Yawn

I certainly hope that this blog doesnt give you the Yawning feeling but actually this is not bad at all. Recent studies have come up with a good theory for Yawning.
Yawning doesnt promote sleeping it delays it! Why, basically the brain overheats after a long day of work (for some) and its needs to get rid of this heat by yawning, it therefore cools the brain! Sending cool blood to the brain serves to maintain optimal levels of mental efficiency.

But why do we do it for no reason when other people do it? Ever noticed it, even thinking about makes me yawn already. Is this normal Dr Bos? Well, yes it is. Another study showed that contagious yawning indicates empathy. It indicates an appreciation of other people's behavioural and physiological state.
In normal words, it basically means that if you yawn at somebody you have a high social empathy, you care about this person. Nothing to do with boredom.
But bear in mind that psychology students yawn more than engineering students.
Funny, I always thought that already...but for the wrong reasons!

The human body is full of miracles and actually the majority is more positive than we think but in any case its keeps a lot of scientist busy working, so no boredom either!
