25-minute walk could add seven years to life

Just 25 minutes of brisk walking a day could add to seven years to your life, heart experts have said. Researchers said moderate exercise could halve the risk of heart attack death among those in their fifties and sixties. The new research, presented on Sunday at the European Society of Cardiology (ESC) congress suggests that regular exercise can delay the ageing process. The German study put men and women aged between 30 and 60 on a daily programme of exercise. They were selected because until then they had not been regular exercisers. The study then tracked key markers of ageing in the blood. Within just six months, these showed changes in the body which help to repair the DNA.
 Experts said just 25 minutes of brisk walking or slow jogging every day could buy extra years of health - and happiness.
