The anti-obesity row is turning sour. Computer games makers have reacted with fury to adverts from government campaign Change 4Life that depict a small boy sitting on a sofa playing with a games console, underneath the headline: “Risk an early death, just do nothing.”

Rather understandably, organisations such as the Entertainment and Leisure Software Publishers Association are a bit miffed at the implication that playing computer games will send children hurtling to an early grave. Perhaps they will soon be running their own adverts claiming that computer games can be part of a balanced diet of hobbies and activities?
