For pensioners who have been following a pioneering health regime for the last 35 years, an ascetic lifestyle appears to be the secret of a fit and happy old age. In 1979, 2,500 men were asked to follow five simple rules – eat well, work out, drink less, keep their weight down and never smoke.
Nearly four decades on, just 25 pensioners have managed to stick to the plan. But they are all far fitter and healthier than the volunteers who gave up.
Those who stuck to the plan have dramatically cut their risk of cancer, diabetes, heart-attack, stroke and dementia.
