The future of this hip replacement is bright. I'm at South by Southwest (SXSW), which has been described as Spring Break for geeks. For the past three days, I've worn a pedometer as I walked around town and around the conference center, just so I can see how I am doing for exercise. Yesterday I walked 15,755 steps, all on concrete. That's the equivalent of 6-7 miles. Although my back is stiff (that's a whole other matter), my hip is fine. So exciting that I can do all this now.
