“Whenever I have to pick something off the floor I bend down, keeping my legs straight. Dutifully touching your toes fifty times every day is a crashing bore. But there are almost as many times when something has to be picked up anyhow — or a lower drawer has to be opened — so I automatically do it in a manner that keeps me fit. I try to make a graceful gesture out of reaching for things on high shelves, too. I don’t make it easier by dragging out a little step stool.”
