Nerve Endings
Nothing really makes you appreciate your skin more than having it scrapped off a large section of your body. Yes, I did something stupid at my softball game last night. I slid into second base, with shorts on.
Normally this wouldn't be such a big deal. You see, we play in the Presidio and the field is all grass. But lately the area around the bases has been getting trampled quite a bit and it was mostly mud. Their solution was to dump lots of sand around all the bases. This solved the whole 'mud' problem, but made my mistake all the more painful. I basically sand-blasted my left shin. Yeah, ouch indeed.
But we won, so it's all good.

Did you look like THIS?

Almost...I can post pix if you want 8-p
OMG - I played softball in jr/sr high school. I still have permascars from sliding into bases. Not much of anything else hurts more than extracting gravel from beneath a few layers of skin. Ouch indeed!
