This book is truly horrifying. Not in the fun, haunted house kind of way, but the kind that makes you feel sick and disgusted with humanity for ignoring or downplaying the dangers of head trauma.
Of course everyone knows that getting hit on the head can be dangerous, but it had long been assumed that concussions were just minor injuries. They're not, as this book goes into great depth to explain. Even head trauma that doesn't lead to a diagnosed concussion can have long term effects, particularly when there are many similar hits over the course of a sports career (think soccer players bouncing balls off their head). I don't understand why any parent would let their child participate in contact sports such as football, hockey, or boxing. But then again, I've never been a fan of those sports. The worst part of course is that many people who do know better - the coaches, doctors, and retired players who have seen and suffered the ill-effects of concussions - still advocate against increased safety standards in football and sports. I am reminded of anti-vaccine crusaders who, despite the evidence that vaccines are safe and save lives, still encourage other parents not to vaccinate their children.
4 stars instead of 5 only because of the format of the book - it seems disjointed, almost like a collection of articles rather than one coherent whole. There are so many individual stories about different people, it becomes difficult to follow along at times.
