haha, but, if you hit your head, your dead. basically. But if you hit your shin, oh dear, a little bit of pain, dont be a pussy, get back on your bike, and ride... i did, with half the skin off my left shin hanging off, sock was all red round the rim of it off the blood, but kept riding lol... maaaaan that was a loooong time ago Its only pain, and a time bit off blood... but if you dont wear guards... after a while, you will get used to trying to keep on pedals, so you dont hit shin, that you wont slip any more... if your wearing guards, you say to yourself, ahh it doesnt matter if you slip, so you will slip... easy as...
