“This suggests that when people exercise regularly，they may be able to slow down

　　the process of aging，” said Sanjay Sharma，professor of inherited cardiac diseases in sports cardiology at St George’s University Hospitals NHS Foundation Trust in London.

　　“We may never avoid becoming completely old，but we may delay the time we become old.We may look younger when we’re 70 and may live into our nineties.”

　　“Exercise buys you three to seven additional years of life.It is an antidepressant，it improves cognitive function and there is now evidence that it may slow down the onset of dementia.”

　　The advice from experts is that everyone should do at least 20 minutes of walking or jogging a day，given the sedentary(久坐的) lifestyles and changes in diet that have contributed to high death rates of heart disease.Exercise can also improve brain functioning.Exercise brings benefits at whatever age the person starts.People who start exercising at the age of 70 are less likely to go on to develop a condition that leads to irregular or racing heart rates in 10 per cent of people aged over 80.

　　“The study brings a bit more understanding of why physical activity has that effect，”said Christi Deaton，Florence Nightingale Foundation Professor of Clinical Nursing Research at Cambridge Institute of Public Health.

　　“It helps us understand the process of cellular aging，as that’s what drives our organ system and body aging，and the effects physical activity can have on the cellular level.”
