I struggled to watch all of that, it was making feel a little queezy (sp?). But that was nasty. I face planted the other day, off the top of a ford fiesta. Luckily the ground was fairly soft. But my helmet definetely helped there. The helmet stopped my nose and face hitting the ground. Instead, my helmet did, followed by my chin. My chin then hit my lower teeth in to my upper teeth (dentist appt. on Wednesday). I was wearing a piss-pot. I was really unlucky that I couldn't get my hands out in time, so I just ended up rolling along my arms. I'll post a video once I've edited it up - it's funny! This is the first injury I've ever had where a helmet would help in the slightest. When I'm doing something, I'm more worried about breaking my legs, crushing my rib cage etc. than I am hitting my head.
