This is new to me and I don’t know what I will say really so I’m just giving it a try. I was always a runner and in pretty good shape for most of my life. Then I hit a bad patch and each day just couldn’t get myself out there to run. I put on weight, which just made me feel worse about myself.

I finally got the running back again after a few years but it was much harder than it used to be and I struggled to get through even the shortest, slowest jog.

I was out in a run the other day and I had almost convinced (说服) myself to give up when I heard someone say, “You can do it! It’s hard, but you can do it!” There was a lady walking the other way and had the biggest smile on her face.

Those words of encouragement at a time when I was ready to give up were like a perfect intervention (干预). I finished my run and now every time I feel like quitting I will hear her words in my head and they give me motivation (动力) and encouragement.

I’ve never seen her again so I’ve never been able to thank her and let her know the effect something as simple as a few words of encouragement from a stranger had and still has on me. It always encourages me in my life and has great influence on my life. I will never forget it and place it in my heart. I will tell it to others and make others believe encouragement is very important to us.

   For many，running has never been their favorite activity. But running can certainly be a great way to get fit and stay healthy.

Getting started is difficult.【小题1】 Running can be boring at times，but the effect on your body and mind is well worth that struggle of just getting up and running.

【小题2】 Every major city and many smaller cities have running communities. They are quite organized and willing to help. They will help you see your running goals through.

Start with short distances. Though the running community would love to have a new long-distance runner tomorrow，the fact is that that will not happen overnight. Try running one mile every day for the next 3 weeks. After that，add it to two miles and so on.【小题3】

Take part in a race. By signing up for a race in the near future，you will focus on a goal and be motivated（激励）to keep practicing for that event. I suggest signing up for a 5-kilometer race that will take place within one month.【小题4】

【小题5】 Motivation is a major factor in running success. Bring a friend along to push you through the times and motivate you in his own way.

   Walking is the best form of exercise. It is good for the upper respiratory（与呼吸有关的）system and the legs. It helps us control our weight and blood sugar. Walking is also a good way to help you make more friends，bringing chances to see new things and meet new people. Personally I try to walk at least 5 miles daily.

As well as walking，I also cycle around Xiamen. Cycling is great for weight loss and helps to build stamina（耐力）.However，cycling does not allow for the same level of social contact as a walk. It is for this reason that I would strongly suggest that you try long-distance walking if you want to be physically healthy. I originally（最初）started walking around Xiamen because I didn't have a car，but I soon started to enjoy the walking for its own sake.

I have also made many friends during my walks. It's not uncommon for my 5-mile walk to sometimes take as long as 2 or 3 hours，because I stop to chat with different shop owners along my route. These days，if I skip my walk for even one day，the people in the shops may want to know why I didn't come.

I' ll never forget the first time some people followed me when I was walking, and asked if it was okay for them to walk with me. I really didn't know what to say, so I just replied that I didn't mind. I have been invited for lunch, dinner and sometimes just to sit and drink tea with total strangers. There is nothing more pleasant than walking past a schoolyard and hearing all the kids say hello to me.

   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.
