My mom worked for a neurological organization when I was growing up, so as a result, we were the kids who weren't allowed to jump on the trampoline or do anything fun without wearing a helmet. In elementary school, this was the equivalent of social suicide, but as I get older, I think my mom might have been on to something. Case in point: A recent study shows that kids falling off their bikes costs the healthcare system $200 Million a year.

Moreover, wearing a helmet reduces a child's risk of brain injury by 85%. So if your kid (or teen) isn't wearing a helmet, why not? Sure, it might make them cringe, but I promise, they'll forgive you one day.
