actually, I've had more. And yes, they are almost all aikido related, but I've been training a long time, and therefore have had ample opportunity to hurt myself. I am sure my aikido injuries are no more than had I been playing soccer, or biking, or other physical endeavors (actually, I've taken some pretty wicked falls off horses too).
Thanks for the well wishes, I'm okay (except my feet are now falling apart, but that has nothing to do with aikido practice, just bunions, ouch!).
