Are you a keen gardener? Do you enjoy regular, brisk walks? Do you swim, run or go to the gym? The good news is that if you exercise regularly, you could end up living longer.

A recent study analysed 5,700 elderly men in Norway. It showed that those doing three hours of exercise a week lived around five years longer than the sedentary. The study, conducted by Oslo University Hospital, found both light and vigorous exercise extended life expectancy.

The report said: "Even when men were 73 years of age on average at the start of follow-up, active people had five years longer expected lifetime than the sedentary."

It added that physical activity was as "beneficial as smoking cessation" at reducing deaths.

"Public health strategies in elderly men should include efforts to increase physical activity in line with efforts to reduce smoking."

Regular exercise could add 5 years to your life
