OK I find this really really shocking! Someone I know was involved in a biking accident recently, he came off and hit his head - he was wearing all the right safety gear, but had a hard peaked hat which jarred his head and neck. He got taken to the American Hospital as he was in severe pain and couldn't move. They tried to make him get up three times saying he'd pulled all the muscles in his neck and had bruising. His parents weren't happy and took him to the Neuro spinal hospital where they discovered he's actually broken his neck!!!! Any sudden movement could have killed him instantly!
How the hell do you miss that?! He now has a head brace to stop him moving and should make a full recovery.
But I'm appalled by this.
