We human beings are quite fond of our brains. They are one of our largest and most complex organs, weighing in at nearly three pounds (2% of our bodies!). Each contains upwards of 90 billion neurons responsible for controlling our gangly, almost hairless primate bodies as well as processing and storing a lifetime’s worth of events, facts and figures. So we protect our brains as best we can, from hats that battle temperature extremes to helmets that buffer even the most brutish blows.
