OW, OW, OW--Sports Injuries

I need to remind myself that I'm not 20-something anymore. I love to ride but I found myself on the ground with the wind knocked out of me tonight. I was going over a fence & was riding a new horse so I wasn't as sure about his jumping style yet, so he jumped big & I was left (which I hate). I thought I had it--thought I could remained balanced, but SHIT!! Off I fall & hit my head & my ass. I know my ego is probably more bruised than my ass but I HURT! Ah well--the hazards of doing lots of sports. Now I'm not sure if I'll be able to spar tomorrow in Taekwondo because my head is sore as well as my hip. If I can't spar then that may be a problem since I am getting ready for my 2nd degree black belt test in June & need all of the practice I can get. Plus I've committed to racing every other Wednesday & would miss the sparring next week. Again, the complications of doing many different sports. I'm just thankful that I can do these sports--but maybe I need to remember that my body isn't as forgiving as it used to be...
