Things to do when cocking up a rock climb: Do not swear at the nice EMT. Do not shake their hand in apology when you do, your forearms will spasm and your hands will clench, hard. Then they will have to be detached with much commotion. Yup, that's a tibia. You might not have seen it before, they have. Don't call attention to it. Try and fall off nearer flat ground, then it won't take so many people to carry you off: http://www.pdmro.org.uk/gallery/p6020034.jpg
