What the shape of your brain says about you

It's the news that will shock grumpy old men everywhere - but we actually get nicer as the years roll by. According to University of Cambridge brain scientists, we become less moody, more agreeable and more conscientious as times passes. The changes are a natural process as the organ matures and come after new technology allowed the scientists to map the brains of 500 volunteers and track any changes over time. The researchers found high levels of neuroticism are associated with increased thickness and reduced folding in some regions of the brain. With colleagues in the US and Italy, they focused on the anatomy of the cortex, or outer layer, where the higher functions that make us human are centred.
