This is somewhat frustrating to me, as I love exercise that makes me feel productive, grow stronger, and work up a good sweat. I love doing push-ups. I love intensity that flushes my cheeks pink and makes me gasp for breath. I love the end of a run or class, when I am happily exhausted, knowing I've given it my all.
However, I know that this time is important. I'll be able to heal and rejuvenate. I'll be able to start running again next week, just in time to kick butt in the Turkey Trot.
What makes you feel old? What is something beneficial that you don't quite enjoy?
