How many hours do you spend sitting in a chair every day? Eight hours in the office and three hours in front of the TV after work is the normal condition for many people.

You probably don't need an expert to tell you that sitting too much is not good for your health, but the following fact can tell you more.

A study showed the health of 123,000 Americans between 1992 and 2006. The death rate(比率)for men who spent six hours or more per day sitting was about 20 percent higher than for men who sat for three hours or less. The death rate for women who sat for more than six hours a day was about 40 percent higher

In other words,

So what can we do about it? Health experts suggest we spend more hours standing instead of sitting.

The BBC and the University of Chester in the UK did a simple experiment with a small group of 10 volunteers who usually spent most of the day sitting. They were asked to stand for at least three hours a day. The researchers took records on days when the volunteers stood, and when they sat around. As a result, there were some great differences, the BBC reported on Oct 16.

The researchers believe that even small movements, like standing while talking on the phone, going over to talk to a workmate rather than sending an e-mail, or simply taking the stairs instead of lift, will help.

“I’ve always had a pretty clear idea of what I want to do.” says Mary, a middle school student who

wants to become a director some day. You may not be as sure of your career (职业) as Mary. But you can start thinking about and planning for your future career.

The following article helps middle school students plan for careers.

Explore (探索) your interests

Many middle school students don’t yet know what they want to do. But in fact, students may change their minds several times, perhaps even after they enter society. And some of tomorrow’s

careers might not exist (存在) today. Focusing on just one job in middle school isn’t necessary. But

looking into the kinds of careers you might like can help you succeed.

Understanding what you enjoy and what you’re good at is the most important step in exploring careers. If you don’t know what you want to do, you should ask yourself what you like to learn about. If you really like science, what do you enjoy about it — the lab work or the research? It’s important to think about what you like to do, because work will finally be a big part of your life.

Discover possible careers

Once you’ve thought about the subjects and activities you like best, the next step is to look for careers that put those interests to use. If you love sports, for example, you might consider a career as a P.E. teacher or a soccer coach. If you like English, a career as an English teacher, a translator or a travelling guide might be a good choice.

After discovering possible jobs, you’ll want to learn more about them. Talking directly to workers on the phone, by email, or through online discussion can help you get information about what they do. Even meeting with them in person is helpful. First-hand information is necessary for you to find out if you’ll really like a career.
