well i not down w/ skull fractures, but as mentioned by others, i don't think the helmets of today are that good.
some don't even cover the ears.
i have fallen on the ground more times than most people.
i have hit my head with and without helmets. i may have had concussions, i don't know. i don't go to hospitals unless someone takes me against my will.
but now i'm at the point were i would like a new helmet but i don't like anything i see.
i think alot of people don't even question the fact that the helmet they have on will do any good. they just assume that if they have a helmet, it will work.
it reminds me of the people that ride motorcycles and wear the smallest helmet they can find just so they don't get a ticket (in those states that have helmet laws)
any helmet is better than no helmet, I think we will all agree on that.
