When I was in hospital,following several days of bed rest, I was delighted to notice a dramatic change in the appearance of my ankles and feet. Much of the usual swelling had gone down, and I could even see the outlines of bones beneath the skin. I came to the conclusion that I should aim to spend the rest of my life with my legs up or walking, saving the periods of having my legs hanging down for meal times. I'm managing to achieve this objective much of the time, with walking still being an occasional activity, because my right leg still complains when I stand on it. I've stopped using my PC and I am writting this on a lap top computer, though I am struggling to cope with the slightly smaller keyboard.
