The other day I came across this site http://youarenotsosmart.com/ . Also came across this Video on youtube http://www.youtube.com/v/btP_vy5cQq4&hl=en&fs=1
Brilliant site and video if you ask me and it got me thinking about how self conscious we are. We perceive ourselves as original authentic unique beings unlike anyone else on the planet yet we discard the fact that we are all from the same blueprint. Your fears are not so different from mine or the dude you pass on the street.
Our brains are machines, albeit biological ones. They have a purpose. Keep us alive long enough to see that we have provided for our offspring well enough for them to provide for themselves. The rest are details.
