A daily walk 'can add seven years to your life'

Just 25 minutes of brisk walking a day can add up to seven years to your life, according to health experts.
Researchers have found that moderate exercise could halve the risk of dying from a heart attack for someone in their fifties or sixties. Coronary heart disease is the UK’s single biggest killer, causing one death every seven seconds, and exercise has long been seen as a way to reduce the risks by cutting obesity and diabetes.
A new study presented at the European Society of Cardiology (ESC) Congress suggested that regular exercise can increase life span. A group of 69 healthy non-smokers, aged between  30 and 60, who did not take regular exercise were tested as part of the study at Saarland University in Germany.
