A promise fulfilled. My father took up yoga at 57. Never health-conscious, he became superbly fit, did a hour of yoga daily, walked for an hour, and died a spry 89 in 2005. I promised myself that when I became older and weaker, I would take up yoga. I have finally attended my first Iyengar Yoga yoga class, and love it. I think it’s going to be my form of exercise.
