Remember kids... always wear a helmet. (The almighty bikeradar helmet thread)

Roxy does the helmet protect his spine? What happens if your boyfriend lose his legs or arms? Helmets don't protect against these potential consequences of a collision, which in my opinion are as likely to happen as massive brain injury...

That's a ridiculous point to make. The fact they don't protect your arms legs or spine is not a valid reason to go without one.
