Don’t smoke, eat your fruits and veggies, exercise regularly and watch your alcohol intake, and you just might live an extra 14 years, according to a new study.

According to the Associated Press, the new study, which tracked about 20,000 people in the United Kingdom, has revealed that adopting these four healthy habits lived an average of 14 years longer than those who didn’t.

Kay-Tee Khaw of the University of Cambridge led the study, which saw benefits in the subjects of the study regardless of their weight or what social class they came from, AP said.

“We’ve known for a long time that these behaviors are good things to do, but we’ve never seen these additive benefits before,” said Susan Jebb, head of Nutrition and Health at Britain’s Medical Research Council, which helped pay for the study.  Its findings were published in the Public Library of Science Medicine Journal, AP said.

Jebb said just doing one of these behaviors helps, but every step you make to improve your health seems to have an added benefit, AP said.

The study looked at healthy adults aged 45 to 79, asking them to track their habits between 1993 and 1997.  The participants scored one point each for not smoking, regular physical activity, eating five servings of fruits and vegetables a day and moderate alcohol intake, AP reported.

Until 2006, the researchers tracked deaths from all causes, including cardiovascular disease, cancer and respiratory diseases. People who scored four points were four times less likely to die than those who scored zero, the research showed.

Khaw said that the study should convince people that improving their health do not always require extreme changes to their lifestyles.

Dr. Tim Armstrong, a physical activity expert at the World Health Organization, said that while the research emphasizes how modifying just a few risk factors can add years to your life, it’s impossible to conclude whether people who suddenly adopted these healthy behaviors would automatically gain 14 years.

‘The 14 years is an average across the population of what’s theoretically possible,’ Armstrong said.

But experts worry that the new findings may still not be enough to persuade people to change their unhealthy ways, AP said.

“Most people know that things like a good diet matter and that smoking is not good for you,” Jebb said. “We need to work on providing people with much more practical support to help them change.”
