Prone to Injury

I don't know what the deal is but tonight was the second week of softball and the second week I injured myself.  Am I just now of the age when everything is starting to go?  Last week was the power sliding into second and leaving half my leg on the field and tonight I was headed to second base and I pulled a muscle in my leg, the thigh region.   It hurts pretty good.  Not enough to take the pain out of my other leg.  No, that aching seems to linger longer.  So looks like another week of nursing injuries.  So much fun.  Maybe it is just life reminding me that I am prone to accidents.
