Even a safe place like a bunny hill can be deadly without proper protection.

Helmets are finally becoming commonplace on ski slopes, but as the recent news has shown us, they are not universal. It's not OK to let your kids ride around the neighborhood without a helmet, and it's not OK to go without yourself. When engaging in activities in which head trauma is a significant risk (biking, skiing, etc.) a helmet can absorb a good deal of the energy of a blow so that your brain doesn't have to. Many other types of head trauma can lead to brain injuries, some of which can be subtle but disabling. This type of head injury may be the most feared, but it's not the most common. At first, the injured person may feel fine, but as the blood accumulates, the patient develops a headache, and rapidly becomes unconscious and dies, unless a neurosurgeon opens the skull. Clinically, the injury can be inapparent until the pressure is sufficiently high inside the skull. It can't burst through the rigid skull, so it simply expands, pushing against the dura mater, and hence the brain, and gives you the above scenario. If you get clonked in the temple, this artery can rupture. Just beneath this thin bit of skull is the middle meningeal artery, between the skull and the dura. One is the "pterion", which corresponds to what is commonly called the "temple". Now, since the skull is pretty tough, it's not all that easy to develop a hematoma like this. The only way to prevent this is to open the skull and let out the blood, thereby relieving the pressure.

If you try to squeeze the entire brain out the foramen magnum, you will die. The medulla contains all sorts of important stuff, including the breathing center. There is only one way out of the skull, and that is through the foramen magnum at the base-and there's already something there: the medulla oblongata. You see, the one way the anatomic protection of the brain can fail is by cranking up the pressure inside the skull.
