“We've known for a long time that these behaviors are good things to do, but we've not seen this benefit before, ” said Susan Jebb, head of Nutrition and Health at Britain's Medical Research Council．“The benefit was also seen regardless of whether or not people were fat and what social class they came from．”

　　Study participants（参与者）scored a point each for not smoking, regular physical activity, eating five servings of fruits and vegetables a day and moderate alcohol intake．

　　Public health experts said they hoped the study would inspire governments to introduce policies helping people to adopt these changes．But because the study only observed people rather than testing specific changes, it would be impossible to conclude that people who suddenly adopted these healthy behaviors would surely gain 14 years．

　　“We can't say that any person could gain 14 years by doing these things, ”said Dr．Tim Armstrong, a physical activity expert at the World Health Organization．“The 14 years is an average across the population of what's theoretically（理论上地）possible．”

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

　　53. Which of the following DOESN'T belong to the four healthy habits?
