Trevor98 the point of a helmet is to absorb the impact from a crash. Helmets are softer than you're skull so that they crumple before you're brains are smashed all over the street. If you're helmet was harder than you're skull it would be like a stuntman using concrete blocks to break his fall, you're skull would fracture and the stuntman would be, well, he wouldn't be in good shape.
KonaRider24, glad you're ok. I crashed recently as well, nothing like your crash but hard enough to leave me a bit dazed. My helmet broke but I was ok, if I hadn't been wearing I would have had a nasty headache and probably a fractured skull.
