You and a pro fighter are a bit of an exception though, Tony. And I’m assuming you were on a mat. If I were running a dojo, I’d mandate headgear when there’s any contact free-sparring on a hard floor. Heads and hard floors don’t mix very well. Hands, feet, chest, etc. is another debate as far as I’m concerned. If you can’t feel a strike enough to know you really want to avoid it, you’re wearing too much gear. I liked bare knuckle back in my 20s and wouldn’t mind it every now and then in my early 40s. I’ve seen a few classmates hit their head on the floor, while it wasn’t too bad, it could’ve been far worse. Concussions aren’t exactly bruises, busted ribs, etc.
