Thanks, all, for the feedback. Sorry for the delayed response, but I had a bit of a setback with a fall and haven't been able to get to this for a few days. Everything is all right, thank goodness and no damage ws done to the instrumentation. I appreciate everything you've said and realize that probably shorter more frequent walks are better. So I'm starting with that now. I've been so blessed this year with all the support I've gotten with the surgeries and I'm grateful for this site and your input as part of it. Hope you all have had a Happy Thanksgiving!
