Fact: you skull is the only bone in your body that cant heal itself.. Just figure'd I'd throw that in, once its broken its broken, you can get a metal plate & screws but the bone still wont heal.. I've got a big a$$ crack in my skull from my eyebrow up over my forhead down to my temple, cant do anything about it... lame... Costs a TON to get that stuff checked out/fixed too.. way more than a helmet..
