Just what I was thinking. Perhaps it is because he is no longer in pain. My sister said to me the other day that I looked younger as I have been pain free since having by 2nd hip replacement.
I'm sure that's got a lot to do with it. Constant pain, as you know, can be so debilitating. Also he's got the huge monkey of Wimbledon off his back now. I'm sure too that his enforced rest was a great benefit to him. I think he needed that break to just let everything sink in and to see the way forward.
