On a personal note, I was plagued by leg injuries throughout July—first my left knee early in the month, then my left heel later on. At one point, the pain was so severe I could barely walk. Consequently, I spent the month hobbling around wherever I went. The cause of these injuries is clear: I practice a martial art called Krav Maga—perhaps unwisely for my age—and whenever I get a bit too enthusiastic, I immediately end up hurting myself. When injured, I wear a solemn expression and wonder if it’s finally time to quit, yet once I recover, I blithely head right back to the gym. There is a saying that “fools don’t learn until they die,” and it seems I belong to that very category. (Kei)
