Pass the Aleve, Please

My legs are really sore today, stiff in places and ways I'm not used to ... calves, inner thighs, quads, glutes and that crease just inside the hip at the top of the leg.

It's not like I never run or go to yoga; granted it's not as often as it used to be.

So I wonder if it 's
a) Sunday's race
b) Monday's rigorous massage/stretching
c) Yesterday's softball
d) I got old all of a sudden
e) All of the above
