As Sir Anthony Seldon stood on the stage, he slipped his jacket down his arms, slid his shoes off and kicked them to the side, chatting away to the audience as though nothing was amiss… then, out of the blue, he flipped himself upside down, into a headstand, balancing solidly, still. “I think I’ll do the rest of the talk this way,” he said, humour in his tone. The great academic from Wellington College was doing a yoga move on the stage and the audience went nuts! Where was this great feat of physical and mental strength happening? At The IPEN (International Positive Education Network) Festival in Dallas, Texas.
