Good lord, DR ELMORE, watch where you're going!
I haven't taken a good header like that in years, but I well remember it is NO FUN.
I have the unfortunate and sloppy habit of occasionally not picking up my feet when I'm out walking somewhere, and I'll catch my shoe on the smallest damned things, like a half-inch-raised panel of sidewalk, or you name it. Those little moments are embarrassing enough, but actually hitting the deck is something that none of us need to be doing. It's good that all you did was skin some skin.
