At 49 I joined an improvisational theater/comedy troupe. Been doing it 7 years now. It has been a big help in dealing with life's challenges. Long-format improvisational theater is basically team storytelling. You have little control over where the story goes or the details, so you must let go of any specific preconceived plans and just roll with it and contribute to the developing story line(s) in a positive fashion.

It's like setting out on an open-ended group bicycle journey. A general direction is chosen and then off you go.

It's also like football/soccer practice. You never know exactly how a game/match is going to develop, but through the honing of skills and the building of teamwork and "group mind" order and meaning is hewn from chaos.
