We had a promotional products fair that we were presenting at at IU today. It was so busy, I was on my feet, in heels, the entire time. My feet are so sore. And I walked to the Y yesterday, and yesterday was the first day of tai chi tou shou (push hands, an interactive style, a bit more demanding). I can feel myself getting stiff. I think I'll go home, soak my feet, and take a nap.
