Did not want to haul my body out of bed this morning. Did not want to get in the car and drive to the Y even though it is little more than 5 minutes away. Did not want to contemplate moving my legs through the aerobic exercises, even in water. But I gritted my teeth and went anyway. A small group this Monday morning (not the usual overwhelming throng) splashed about for an hour in the blessed quiet of the natatorium. By the time class was over, I felt loose, even limber, with no more aches or pains ambushing me.
