This is my PA Don. We’ve worked together for about 24 years. As with all things brain, folks have a fascination with the head and it’s precious contents. So someone gave him a bicycle helmet with a brain decal. As you can see it’s called a brain bucket. The actual truth is that if you fall hard enough this bit of Styrofoam will not save you. A colleague was found by the roadside and had sustained a career ending subdural hematoma. In my opinion the helmet is better than nothing at all but a serious concussion will still be a problem no matter what you wear.
