The study found those who exercised just 15 minutes a day - or 90 minutes a week - cut their risk of death by 14 per cent and extended their life expectancy by three years compared with those who did no exercise.
Researchers kept track of their progress for eight years on average and calculated projected life expectancy. Based on their answers, they were put into five groups of varying activity levels from inactive to highly active.
