pain is our perception of waht we feel to the touch. We feel pain mostly when we are not paying close attention to the environment. This having to do with our survival skills as primates in evolution. Throughout evolution our pain receptor and preceptors have been warped over time to protect us from our enemies and to be on our guard for our pray. I have posted a video to the recent imbeciles of our world today who express the gruesomest pain yet. The video has been made from 2010. enjoy.
It is hilarious... laughed for a full half hour :)
