Call it what you will, Robb's got it.
He said to me last night that if he hadn't become so stubborn since his accident, he is certain that he wouldn't be walking as much as he is. Robb is at the pool three times a week, and cycles on the remaining sunny days. He's moving those muscles around, and hopefully stimulating more nerve regeneration.
The odd thing is that during the last few months, when I was laid low with hepatitis, I was trying to exert myself as little as possible, to speed my recovery. So, while Robb was being as active as possible, I was being a total slacky lay-about.
Strange how our two afflictions should have such different treatments.
