My history in athletics is pretty dismal. Lack of talent and coordination made me the last chosen for every team, and no matter how much my classmates and friends cheered (“C’mon, Marlys, you can do it!”), the volleyball I served or the baseball I hit would travel a few feet and then fall to the ground as though made of solid lead. But I did excel on the playground. I could swing, teeter-totter and slide with Olympian panache and even make my way across the tallest rungs of a jungle gym.
