Have you ever considered how many ways there are to suffer a head injury? We have and our conclusion is that there are a lot! From collisions playing sports, to slips and falls, to motor vehicle accidents, your head is always susceptible to a hard knock. Whether it leads to a brain injury though depends on the severity of the blow.
Most people mistakenly assume that a brain injury only occurs after receiving a severe blow to the head such as slipping and falling on concrete or being sacked while playing a sport. But the brain can suffer an injury even after a slight knock to the head. This happens because the force exerted on the body causes the brain to move inside the skull, sometimes colliding with it and causing damage.
