"Keeping the body in good health is a duty，otherwise we shall not be able to keep our mind strong and clear." This saying by Buddha is a life motto of highly healthy people. 【小题1】The following four habits will significantly improve your health.

They are organized and disciplined.

If you want to be healthy，you should try to become organized. 【小题2】It will help you succeed in everything and do things on time.

【小题3】

In our busy lives，it's very easy to ignore the healthy habits that keep us feeling great and eating right. Highly healthy people usually have a habit to prioritize（优先考虑）their health. They are particular about their nutrition. They always avoid fast food because they find it very harmful.

They have an exercise schedule.

Exercise and other physical activities are not only good for you，but they are also a fun way to spend time. 【小题4】That's why they set aside time for exercise in the mornings or evenings. Due to the high level of self-organization，they easily stick to the exercise schedule. They think that active lifestyle and regular sports will help them live longer.

They get enough sleep.

Sleep plays an important role in immune（有免疫力）function，memory，learning and other important functions. 【小题5】 It is very important to wake up and go to sleep at the same time，because your body works according to a certain rule.

   If you cut down on the time you spend sitting，you might live longer. New research shows that sitting less than three hours a day might extend your life by two years.

【小题1】 But modern lifestyles and office jobs rarely give us the chance to move around. Sitting is something we do all the time and everywhere. We sit while we're eating，we sit in the car and we sit while we are watching TV. And many of us sit for many hours at work. So on average，Americans report that they sit between four and a half to five hours a day.

Exercise is important. But so is not sitting.

You may exercise often. But it does not mean you can sit for the rest of your waking hours. 【小题2】 Even if you exercise for 30 minutes a day，what goes on in the other 23-and-a-half hours a day is also very important，according to a study on how sitting all day affects the length of life. It shows that cutting television time to less than two hours a day could add one point four years to life.

【小题3】

Change is already coming to some offices，especially in the design of desks. A "standing desk" lets people stand while they work. Another new design is called the "treadmill（跑步机）desk". A treadmill is an exercise machine that lets you walk in one place. Even some U.S. schools are beginning to experiment with desks that are part bicycles to keep children moving.

Exercising while working.

【小题4】They may have got five "standing desks" for their employees or a "treadmill desk". Some other companies may not buy one for everybody but they'll have a bank of these desks where people can go for an hour a day and answer their emails or talk on the phone. People are really trying to limit the amount of time spent sitting at the desk.

Suggestions for sitting less.

If you work in an office or have a sedentary（久坐不动的）job，scientists suggest a few simple changes. Get up from your desk as often as you can. 【小题5】 Instead of emailing colleagues，walk to their offices and talk directly. If you are sitting down reading this，stand up. Move your legs. Touch your toes，if you can. Do anything but sit.

All these activities may help you live longer.

   When it comes to exercise，most of us fit into one of the two groups — those who keep a regular exercise habit and those who think about being more active but can’t seem to have a plan to do it consistently. Whatever your attitude to exercise，there’s another form of physical activity that many of us car-loving people can do to get enough movement in general.

Studies have shown that putting away your car and walking, biking or taking public transport to work can have a significant positive influence on your health by improving spirits, reducing body weight and lowering the risk of heart disease.

It’s not surprising that taking a bus or a train regularly leads to a more physically active lifestyle. Just think about what comes with using public transport. Those who travel to work without a car walk to stations, climb stairs, often stand while waiting for their bus or train, and then finally travel on foot or by bicycle to their destination. Such active transport can make up for the inactive time spent in work and school environments.

There’s no doubt that the improving public transport system in the city is influencing the way people work and live. But though the public transport system is improving, it is not within easy reach of everyone who would like to use it.

Bike-sharing programs are also growing in popularity（普及）and helping to bridge a gap in the crowded city public transport system. These programs allow users to easily book, ride and return a borrowed bike. Bike-sharing programs help people who might still need to travel some distance between the end of the bus or the underground line and their final destination. They also offer an opportunity to residents and visitors to travel freely around the city without being trapped in a car.

   An increasing number of Chinese are jogging to get and stay fit. Most joggers will run alone, but some will jog with friends or even coaches.

The Beijing Olympic Forest Park is one of the most popular spots. It is packed with runners in the afternoon, usually after work, and at weekends.

Jogging after a whole day’s work can be a way to unwind. It is true for He Wenjun, whose workplace is right near the forest park. She discovered her athletic gift at the age of seven, when she began playing tennis. Then she turned to jogging, and she has persevered with it for 10 years. “I come to jog almost every day after work, whenever I have time. I think jogging is good for my health. And for me, a girl, it helps me to achieve to keep slim,” she said.

She says she prefers jogging alone, so she can focus better. She loves jogging, even during Beijing’s smoggy days. “If the smog is severe, I’ll hold off jogging for a while. But if I really want to get away from work, I’ll wear a mask, or just ignore the smog and go on jogging,” she said.

For those who are not so athletic, jogging also has its attractions.

Wu Houbin started roughly two years ago, when he was severely obese（病态肥胖的）. Within two months, his weight dropped from 82 kilograms to 64 kilograms. The success helped him recover health, and he has made friends. “Jogging does not require speed, but perseverance. If you want to stick to the game, you need to take it as a task, a habit, and then eventually a hobby,” Wu said.

Jogging is beneficial to heart-lung function, and the skeletal system, but doctors say improper technique damages the joints, especially the knees and ankles. “Excessive jogging wears down the body, and harms one’s health. Poor technique harms the muscles and skeletons, and can cause secondary injuries. And, jogging in a bad environment can cause circulation problems,” said Lu Zhiyong, attending doctor, Sports Hospital, General Administration of Sports.

Dr. Lu has some tips for joggers, and those who are thinking of taking it up.

He says people should first evaluate（评估）their physical condition, to decide the amount and type of exercise, and jogging in the open air is better than running on a running machine. It is recommended that joggers jog three or four times a week, and 30 to 60 minutes each time. The best time to jog is 4p.m. — 5 p.m.
