When I was growing up, children were constantly dying from brain injuries sustained in tricycle accidents; I personally lost 12 classmates. This is why today children wear protective gear 24 hours a day. So I was shocked to learn of a recent study which conclusively proved helmets to be unnecessary unless your toddler plays in traffic. There is apparently a piece of anatomy called the “skull” which is filled with a brain-protecting fluid specifically designed for this purpose, and which is extra robust in children. The study tested 100 billion humans over a period of 250,000 years.
