Men can add five years to their lives by walking for 30 minutes a day six times a week, it is claimed. Researchers said regular exercise is as good for health as quitting smoking. Half an hour of daily physical activity—be it walking, cycling or swimming—cuts risk of early death by 40%.

The research, which involved 6,000 men in their 60s, 70s and 80s, found less than an hour of light activity a week did not significantly lengthen life. Researchers found men who quit smoking had up to 41% less risk of death than those who smoked.

They wrote: “Even when men were 73, active persons had five years longer expected lifetime than the sedentary.

Meanwhile, another study found that Britain is among the worst in Europe for sitting around all day.

Most of us spend more than eight and a half hours a day not stirring from our desks. Spending too long sitting raises the risk of heart disease, now Britain’s biggest killer.

Nearly half of us admitted to doing nothing at all, a doctor said: “There is growing evidence to suggest that sitting for prolonged periods can increase your risk of developing heart disease.” “Breaking up long periods of sitting can make a real difference to your health.” “Even making small, more active changes to your routine can improve your heart health.The lighter evenings in summer is the perfect opportunity for people to start to make these changes.”
