After the lunch whistle

Every yard has a quiet hour. Ours starts when the lunch whistle goes and lasts until somewhere past two. The forklift is parked, the crew sits on the tailgate of the flatbed, and the day, which was moving well at ten, seems to have been set down and not picked up again. Men in their fifties know this hour at a desk too, and they know it costs them more than it used to.

What changes in the body after a midday meal is not mysterious. Digestion draws on the same reserves that attention does; a large, heavy plate followed by sitting still is a recipe for the eyes to close, at any age. The body's daily rhythm also has a natural low in the early afternoon, independent of lunch, which is why cultures in hot countries built a rest into that hour long before anyone measured it. What seems to change with age, according to the men who write to us, is the depth of the low and the time it takes to climb out of it. A man of thirty shrugs it off by half past two. A man of fifty-five can lose the afternoon.

What the yard changed, and what it kept

The yard kept the rest. Trying to work straight through the quiet hour produced mistakes with the forklift and short tempers at the dispatch line, so the break stays. What changed was the shape of the meal and the shape of the task that follows it. The crew eats earlier than it used to and eats less at one sitting; the men who bring a second, smaller portion for mid-afternoon say they prefer it to one big plate. The first job after the break is never the hardest one of the day. It is something with the hands, in the open air, short enough to finish: moving a pallet, hosing the mixer, walking the stacks with the order sheet. The hard thinking, the pricing and the planning, gets done before lunch or after three.

Readers have described the office equivalent in almost the same words. The meeting that matters goes in the morning. The first thing after lunch is a walk to the far end of the building, a short errand, the kind of task that can be finished in a quarter of an hour and leaves a small sense of having done something. The slide, they report, is not abolished; it is shortened, and the afternoon is caught before it reaches the floor.

The distance between the last meal and sleep

One more thing the yard noticed, which the research on daily rhythm backs in general terms: the afternoon is partly decided the night before. A late, heavy evening meal and a short sleep make the next day's quiet hour deeper. The crew that eats early at night wakes easier and dips less at two. We will say more about the evening in the last note; here it is enough to notice that the two ends of the day are tied together, and that a man who only tries to fix the afternoon is working on the wrong end of the rope.
