Your chair is your enemy. That is the conclusion of several recent studies. Among people who sit in front of the television for more than three hours each day, those who exercise are as fat as those who don’t.
So what’s wrong with sitting? The answer seems to have two parts. The first is that sitting is one of the most passive things you can do. Compared to sitting, standing in one place is hard work. To stand, you have to tense your leg muscles, and engage the muscles of your back and shoulders; while standing, you often shift from leg to leg. All of this burns energy.
You may think you have no choice about how much you sit. But this isn’t true. Suppose you sleep for eight hours each day, and exercise for one. That still leaves 15 hours of activities. Even if you exercise, most of the energy you burn will be burnt during these 15 hours, so weight gain is often the cumulative(累积的) effect of a series of small decisions: Do you take the stairs or the elevator? Do you walk to the corner store, or drive?
But it looks as though there’s a more sinister aspect to sitting. Some evidence suggests that when you spend long periods sitting, your body actually does things that are bad for you.
Lipoprotein lipase(蛋白脂酶) is a molecule that plays a central role in how the body processes fats. Low levels of lipoprotein lipase are associated with a variety of health problems. Studies in rats show that leg muscles only produce this molecule when they are actively being moved. The result is that when you sit, an important part of your metabolism(新陈代谢) slows down. You may also have a higher risk of suffering from diabetes(糖尿病).
Some people have advanced radical solutions to the sitting syndrome(综合症): replace your sit-down desk with a stand-up desk, or watch television in a rocking chair. But whatever you choose, know this. The data is clear; look out for your chair.

A young man was complaining about his bad luck and poverty. He frowned (皱眉) all day. A wise old man came to him and said, “Hey, kid, why are you so unhappy?”

“I don’t understand why I'm so poor!” he replied.

“Poor? I think you are very wealthy!” the wise old man said sincerely.

The young man was puzzled, “Why do you say that?”

“Supposing someone offers you one thousand dollars to cut your finger off, would you do it?” “Of course not!” the young man replied.

“And ten thousand dollars to chop your leg off?” “Certainly not!”

“A hundred thousand dollars to scoop your eyes out?” “Surely not!”

“One million dollars to turn you into a 90-year-old man immediately?”

“Definitely not!”

“Ten million dollars to take your life right away?” “Absolutely not!”

The wise old man said with a smile, “So there you are. You already possess what is worth more than ten million dollars. Why are you still sad to be so poor?” After the young man listened to the wise old man's words, it started to become clear to him.

When I was four years old，I broke my elbow. After many weeks in a cast (石膏) I returned to the hospital to finally have it removed. My mother found it strange that I was so enthusiastic about returning to the place where I had experienced so much pain. Yet she soon discovered my fas­cination with the healing process and how doctors helped to enhance it.

I was in fear as the doctor removed my cast and asked me to move my arm，and immediately became scared as the pain came shooting back through my elbow. After another series of X-rays and examinations my arm was put into a new cast I had begun to doubt the reliability of the doctor，and my mother thought I would be unwilling to return a second time.

When the day came to have my cast removed again，I was nervous. Yet I was optimistic enough to trust the doctor as he once again removed my cast and asked me to move my arm. And this time it was better! Nothing hurt!

On the way back home I released (松开) my mother's hand and ran ahead，and out of her sight. She was immedi­ately worried that I would come upon someone dangerous. At the age of four I was already known for liking to talk with strangers that I felt were potential friends. When she caught sight of me again， I was looking up into the face of an old broken-legged man，saying，“Don't worry，sir! The doctor will fix your leg. Look how he fixed my arm！” 

Since then I have continued to be fascinated with the human body and medicine. I also still love to help people，and never miss an opportunity to encourage someone. But most of all，I still believe that optimism and trust are the building blocks of happiness and success. Many things can change，but I am proud to say that these parts of me have always stayed the same.
