Helen sat down with a sigh. It was time to think of a new year’s resolution.

Why do I do this to myself? she pondered. Each year promising myself to do something useful. My spare room is filled with things from years past. The cross stitch still unopened, the exercise bike which I generally hang my ironing on. Shelves stacked with books I never get round to reading, exercise videos that maybe were watched once, and I nearly put my back out with them.

Think I must have tried every avenue to a healthy life. It cost me a fortune in gym membership, even personal trainers. They all fell by the wayside. Even tried volunteering with charities, every time finding out I couldn’t give them the time required with my work schedule.
