Ten things we don't understand about humans

I was reading my blogs today and ran across these articles on New Scientist. Thought that I would share them with you. ^_^ Enjoy

Blushing
I always thought that blushing was a way to show some form of excitement. Why else would women spend so much money on rouge every year? As a species, blood rushes to the surface of our skin when we are sexually aroused so what is to say that it will not do the same when we are excited in other ways as well?

Laughter
In my opinion, laughter is meant as a form of defense (ie nervous or embarrassed laughter) or a form of bonding, such as laughing together over an inside joke.

Pubic Hair
'Nuff said

Teenagers
My thought on this one is that the teenaged years were a time for the child to individuate from the parent and thus offer a greater chance for survival.

Dreams
In my opinion, dreams are a time for us to allow the subconscious mind offer assistance to solving issues that the conscious mind is having trouble with. They also seem to be a way for us to relive the days events and put them in perspective.

Altruism
Personally, I do not think that there are any true altruists. Even if you are doing something because it is good to do, you are still getting a sense of "do-gooding" out of it.

Art
OK - sometimes, this one escapes even me. There is quite a bit out there that is considered "art" that I personally this is nothing but utter crap.

Superstition
Superstition is an interesting subject. One thing that it seems to be is a form of causal determination, such as wearing the same shirt to every game since that was the shirt that you were wearing when your team won the big game.

Kissing
This seems to relate back to bonding. It seems that when we were born, our mothers would kiss us and therefore, kissing brings back similar feelings.

Nose-Picking
OK - you got me. I have nothing to add to this one. LOL
