Jim Sweeney can't stand up for falling down. He has the auto-immune disease, multiple sclerosis. Essentially your body is attacking itself - which means that if you are looking for someone to blame, it's you.
The patron saint of ice skating was a 14th-century nun. She was also the first recorded sufferer of MS. Sweeney can't ice skate. He can barely walk. When he does manage to shuffle along, passers by think he is drunk - and his vision is so blurred that the entire world looks like a Monet painting.
What hasn't deserted him is his sense of humour. Sweeney's quiet musings on the nature of illness and the perils of bad acting are told with a directness and sharp humour that is enormously engaging. Like all really good shows, it is about much more than it appears. It is a brief hour not about how to live with MS, but about how to live - with or without legs that work.
