I got thrown off a horse recently and my head hit the ground so hard the riding helmet cracked. Scary shit. Idk if I'd even be alive rn if I wasn't wearing it.
I had a banana fall in derby once and fell right on my head. My mouth guard and S-1 Lifer helmet prevented me from getting a concussion. If you're doing anything on wheels without a seatbelt, you gotta wear your helmet.
