For better health, many people turn to doctors or self-help books．But they don’t realize that their friends could help them fight illness and sadness, slow aging and help them live a longer life．Researchers are only now starting to pay attention to the importance of friendship in whole health．A 10-year Australian study found that old people with a large circle of friends were 22 percent less likely to die during the study than those with fewer friends．

“In general, the role of friendship in our lives isn’t well appreciated,” said Rebecca G．Adams, a professor of the University of North Carolina．“Friendship has a bigger influence on us than family relationships．” Why friendship has such a big effect isn’t clear．While friends can pick up medicine for a sick person, the advantages go well beyond physical help．

Last year, researchers studied 34 students at the University of Virginia, taking them to the foot of a steep（陡峭的）hill and fitting them with a heavy backpack．They were then asked to estimate the steepness of the hill．Some of them stood next to their friends during the research, while others were alone．The students who stood with their friends judged the hill to be lower than the hills in other students’ eyes．And the longer the friends had known each other, the less steep the hill appeared．

“People with stronger friendship feel like there is someone they can turn to,” said Karen A Roberto, director of the medical center at Virginia Tech．“Friendship is a great resource, but many people don’t realize it．The message of these studies is that friends make your life better．”
