Spot the difference

There is hardly any, except for the hair. Yogacharya B K S Iyengar, who turns 90 this weekend, is as fit as he was at the time the photograph was taken decades ago. Even at this age, he practises yoga for three hours and pranayam for an hour. On Wednesday, students from New York to Mumbai trooped in at the Yashwantrao Chavan Hall at Kothrud to honour their guru, who was also appointed the president of the Indian Yoga Association. He inaugurated an exhibition to flag off the birthday celebrations.
