>>18855661) bike helmets and boxing headgaurds are two very different things, one's a foam thing that you can punch without fucking up your hand and the other's a rigid thing that's supposed to protect against asphalt not padded fists
2) I the context of biking, "Diffusing the blow" is actually a good thing, and it's a bad thing in boxing because it allowed people to take more headshots in a single bout where they would usually stop. This isn't really a consideration for bikers unless you're saying "wow I feel relatively fine after crashing, let me go intentionally crash more times in the same day"
As an aside, why the hell is a cardiac surgeon doing neorology/sports medicine shit?
