Thank you. I have to tell you, yesterday I went to my volunteer position at our local hospital emergency room. The hospital has been undergoing major renovation and we have an entire new wing and main entrance. Went over to check it out with another volunteer and saw the huge amount of stairs going up to the second floor......Did they have an elevator, yes, but I decided to try the stairs. We did GREAT. All the way up, walked around the new med/surg unit, and all the way back down. Before knee replacement, I definitely would not have tackled that, it would have been the elevator. I do think our "dog walk" is the best medicine, both for our body and soul.
