To get an extra 14 years of life, don’t smoke, eat lots of fruits and vegetables, exercise regularly and drink alcohol in a proper amount. That is according to a study published this Monday in the Public Library of Science Medicine Journal.
After tracking more than 20,000 people aged 45-79 years in the United Kingdom from about 1993-2007, Kay-Tee, Khaw of the University of Cambridge and his colleagues found that people who adopted these four healthy habits lived an average of 14 years longer than those who didn’t.
“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．”

Why does most of the world travel on the right side today? Theories differ, but there’s no doubt that Napoleon was a major influence. The French had used the right since at least the late 18th century. Some say that before the French Revolution, noblemen drove their carriages on the left, forcing the peasants to the right. Regardless of the origin, Napoleon brought right-hand traffic to the nations he conquered, including Russia, Switzerland and Germany. Hitler, in turn, ordered right-hand traffic in Czechoslovakia and Austria in the 1930s. Nations that escaped right-hand control, like Great Britain, followed their left-hand tradition.
The U.S. has not always been a nation of right-hand rivers; earlier in its history, carriage and horse traffic traveled on the left, as it did in England. But by the late 1700s, people driving large wagons pulled by several pairs of horses began promoting a shift to the right. A driver would sit on the rear (后面的) left horse in order to wave his whip with his right hand; to see opposite traffic clearly, they traveled on the right.
One of the final moves to firmly standardize traffic directions in the U.S. occurred in the 20th century, when Henry Ford decided to mass-produce his cars with controls on the left (one reason, stated in 1908; the convenience for passengers exiting directly onto the edge, especially… if there is a lady to be considered). Once these rules were set, many countries eventually adjusted to the right-hand standard, including Canada in the 1920s, Sweden in 1967 and Burma in 1970. The U.K. and former colonies such as Australia and India are among the western world’s few remaining holdouts. Several Asian countries, including Japan, use the left as well — thought many places use both right-hand-drive and left-hand-drive cars.
