This was the moment an elderly man at Massachusetts Avenue train station started an impromptu Tai Chi session with fellow travellers on Saturday (May 25).<br /><br />Initially, the man was practising the ancient Chinese tradition alone but garnered the attention of Bostonians who joined in on the exercise.<br /><br />The filmer commented: "He typically does it solo in the park, I have seen other people doing it with him occasionally."<br /><br />They later said: "I was doing the workouts for a little but it seemed like a surreal moment that I wanted to capture."
