Helmet versus nude melon

[PBO]

In Australia we are 'forced' to wear helmets when we ride bicycles. I personally wear one & very willingly, so I have no hesitation making sure my kids do also

Anyway, there's a vocal minority of riders who are anti helmets & the legislation that makes wearing them compulsory. They cite all sorts of information that supports the theory that wearing them is actually more dangerous. From my personal experience I cannot see any merit in the anti helmet propaganda or theories

Anybody have any theories or opinions on the subject?
