My wife and I were visit the YMCA several times a week for water aerobics and other forms of suffering. One unsupported observation I’ve made is that women represent the majority of those who swim laps for exercise. Also, some of the most broken down looking people are great at swimming laps. Seems that when they get into the relative weightlessness of the pool their bodies make some transformation. I watched an older woman today hobble into the pool and then begin gracefully gliding through the water for forty minutes. There certainly is a lesson here for us all.
