Yep, actually, I just came on to post that I talked to him last night (Sun. 3/16) for a bit. He sounds good, stronger than the day after surgery, and that he has been using the standing machine for different intervals. His biggest kick right now is being taller than his wife for a change!
He seems to feel pretty good, all things considered, and is quite anxious to get on with it and again enjoy his freedom.
He didn't say, but I have a feeling that he's been lurking around here during his down times, so feel free to mock and abuse him all you want— it's good therapy for his sense of humor— trust me!
