Elderly man starts impromptu session of Tai Chi at Boston train station

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).

Initially, the man was practising the ancient Chinese tradition alone but garnered the attention of Bostonians who joined in on the exercise.

The filmer commented: "He typically does it solo in the park, I have seen other people doing it with him occasionally."

They later said: "I was doing the workouts for a little but it seemed like a surreal moment that I wanted to capture."
