"According to many studies over thousands of years, movement shapes the human body. Today humans have a brain that is about three times larger than would be expected given our body size. Our brains were shaped and sharpened by movement and we continue to require exercise in order for our brains to function optimally. It is generally agreed that the brain was driven by need to think but some scientists are now suggesting that exercise played a critical role in making our brains larger."
