The brain is split up into two symmetrical hemispheres. While they do work together, the left brain favors more rational, analytical thinking, while the right is more visually and conceptually oriented. They also work in opposites – you stub your left toe and the “pain” is processed on the right side. And they put right-side-up whatever is upside-down – the image in your eyes is actually received inverted and the brain corrects it. But here's the REALLY weird thing – even if you were to lose one-half of your brain, you would be able to survive without it. Well, maybe that's not so weird – look at all those stupid politicians!
