Just in case you thought you were invincible....
A jolly good read for all the family, involving high speed skin contact with asphalt.
If you ride for long enough, at some point, parts of you are going to make contact with the road. It might be your fault; it might not. It doesn't matter - we're all going down at some point.
I have a few slightly less gruesome photos of my own lurking in the family albums. The worst part is not the scraping along the road - the shock tends to numb the pain. The worst part is when the big Maori nurse turns up with a stiff scrubbing brush and a bucket of Dettol and starts scraping all the bits of rock, sand, glass etc out of your skin. By that time, the shock has worn off, and it just plain hurts. And you know that if you want to heal properly, you just have to grit your teeth and bear it.
