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

I think the point he's making is that you're as likely to paralyse yourself by injuring your spine in a crash, or put yourself in a wheelchair by damaging your legs and yet nobody complains about us not using motorcycle style spine protectors or even arm and leg protection.

While that is a valid point, I disagree with a bit there, because for instance if you've lost your leg during an incident, at least you're not brain damage, personally I would rather lose an arm or leg than be brain damage and not be able to function properly, or at all.

the spine is a different thing thought.
