Draw the draft

And two days later, he would run.… At seventy-two, Kenji had become very good at walking. Every morning, shortly after sunrise, he put on the same pair of walking shoes and left his apartment. He walked along the river, past the convenience store, beneath the rows of trees that had been planted when the neighborhood was rebuilt decades earlier. He did not walk quickly. There was no reason to. He had learned that walking was one of the simplest forms of exercise he could give his body. It raised his heart rate without frightening him, loosened his hips and ankles, and gave him a reason to leave the house. On days when his thoughts were heavy, twenty or thirty minutes outside seemed to rearrange them. The doctors and exercise specialists he occasionally read about were not asking people his age to become athletes.

Later that week, when I recounted the ordeal to an acquaintance—explaining how a simple refusal to turn on the AC had culminated in an elbow twitch, a near-fainting episode in the garden, and an emergency regimen of oral rehydration therapy—they list By early July, the summer sun had settled over the neighborhood with stifling intensity, sending ambient temperatures soaring into the mid-90s with humidity levels to match.

Assuming it was merely a stubborn muscular knot or a pinched nerve from sleeping awkwardly, I spent the afternoon flexing and extending my arm, trying to work out the involuntary flutter through basic range-of-motion stretches. Two mornings later, the heat reached a oppressive crest. Ignoring the suffocating air...

Mika could feel heat radiating through the soles of her shoes as she crossed the service entrance. The summer festival had brought thousands of people into the city, and the temporary food stalls were working without a break. Even under the tent, the air barely moved. Her supervisor, Sato, handed her a bottle of water. “Drink.” “I’ve been drinking all morning.” “Then drink some more.” Mika laughed. “I thought too much water was dangerous.” Sato shook his head. “That depends on the circumstances. Heat illness isn’t simply about not drinking enough water. You lose water and electrolytes through sweat, and what you need depends on how much you’re sweating, how hard you’re working, and how long you’re exposed to the heat.” That summer, Japanese...
