Say you meet with difficulty, what’s the first thing you do? Call your best friend and ask for help? It turns out that doing this may be better for you than you think. Researchers find that friendship has a big influence on your health, well-being and business.

One study from scientists recently found that older people with a large circle of friends were 22% less likely to die during a 10-year period than those with fewer friends. Other researchers discovered that having a strong social network could improve brain health as we age.

Even more interesting, feeling close to your friends may give you a different view on things. Researchers gathered 34 college students out side and asked them to estimate the steepness(估计陡峭程度) of a hill after climbing it. Those standing with friends gave lower estimates, and the longer the friends had known each other, the less steep the hill appeared.

What is the reason that friends can make obstacles seem less difficult? “People with stronger friendship networks feel that there is someone they can turn to,” said Karen A. Roberto, director of the center of the hospital at Virginia Tech. “Friendship is a valued resource (宝贵的资源).”

It is truly the fact. Friends make your life better. They provide support in hard times. They inspire you to make changes in your life, encourage you to set goals and cheer you on every step of the way until you reach them.
