 Despite the demographic problems, Paul, of old people staying alive, you are an advocate for staying moving. I think walking is the most wonderful thing. I'm not really a cricket fan, despite trying to teach my father, but I spend a lot of time in the Pyrenees, and it's incredibly life-enhancing. The other day, my wife and I went up the Canigou Mountain, which is the sacred mountain of the Catalans, surprisingly. As you do.
