It was really bad on Saturday. In spite of which I went for a longish, wrenchingly uncomfortable walk along the Rochdale Canal in Failsworth. I have never felt so old. I had a walking stick with me and was trying not to hobble. I nearly didn't go but then Ailz said something inspiringly stoical and I thought, "No, the night is coming when no-one can work (Biblical, innit?) but it's not here yet and while I can I will."
