I know some guys who are softball pitchers (wait, I'm going somewhere with this!) and they used to get cuts and abrasions on their hands from the seam on the ball so what they were told to do by a coach was to urinate on the parts of their hands that were being subjected to the most punishment (usually the knuckle area on the thumb) and apparently this worked very well, it hardened up the skin on their hands and prevented the skin breaking, of course nobody wanted to shake hands with them anymore but that was a small price to pay. I guess there's some kind of chemical in urine which helps to toughen up the skin or something like that so I'm wondering if this technique would work with the shins, anybody wanna try taking a piss on theirs and then report back on how successful it was, you can finally put those last dribbles to good use!?! :-D
