Feel tired lately? Has a doctor said he can't find anything wrong with you? Perhaps he has sent you to a hospital, but all the advanced equipment there shows that there is nothing wrong with you
Then, consider this: you might be in a state of sub-health. Sub-health, also called the third state or gray state, is explained as a borderline state between health and disease
According to the investigation by the National Health Organization, over 45 percent of sub-healthy people are middle-aged or elderly. The percentage is even higher among people who work in management positions as well as students around exam-week
Symptoms(症状) include a lack of energy, depression, slow reactions, insomnia, anger, and poor memory. Other symptoms include shortness of breath, sweating and aching in the waist and legs

As for meals, people are advised to eat less salt and sugar.

.”For years scientists have been worried about the effects of air pollution on the earth’s natural conditions. Some believe the air inside many houses may be more dangerous than the air outside. It may be one hundred times worse.
Indoor air pollution can cause a person to feel tired, to suffer eye pain, headache and other problems. Some pollutants can cause breathing disorders, diseases of blood and even cancer. Most scientists agree that every modern house has some kind of indoor pollution.
People have paid more attention to the problem now. It is true that when builders began making houses and offices they did not waste energy. To do this they build buildings that limited the flow of air between inside and outside. They also began using man-made building materials. These materials are now known to let out harmful gases.
As the problem became more serious, scientists began searching for a way to deal with it. They discovered a natural pollution control system for building—green plants. Scientists do not really know how plants control air pollution. They believe that a plant’s leaves absorb or take in the pollutants. In exchange the plant lets out oxygen through its leaves and tiny organizations on its roots. Scientists suggest that all buildings should have one large plant or several small plants inside for every nine square meters of space. Studies of different plants show that each absorbs different chemicals. So the most effective way to clean the air is to use different kinds of plants. Having green plants inside your house can make it a prettier and more healthy place.

Sitting in the play area of the doctor’s office, my children, Paul, four, and Bailey, three, built a Lego tower while we waited to be called for Paul’s examination.
“Good job, you guys,”I said, trying not to sound too tired. My husband was away on business, and it was difficult being alone with the kids. At times I felt like I was living in the jungle(丛林) rather than the suburbs.
“Don’t put the Lego in your mouth, Bailey,”I said. Paul grabbed(抓取) it from him.“That’s not nice, Paul,”I said. He gave back the Lego. I looked around the waiting room. A woman was eating something, a couple were talking, and an old gentleman in a blue jacket was reading a magazine. I wished I could sit quietly for a while. I wanted to be able to take a rest, or go shopping alone. At once, I was ashamed of myself. What kind of mother was I? “God,”I thought, “help me to be the very best mom I can be.”
The nurse came into the waiting room to get us. Just at that moment, the old gentleman in the waiting room put down his magazine and came up to me. With a smile on his face, he said, “Your children are most certainly lucky to have such a wonderful mother.”“Thank you,”I replied in a low voice and watched him walk back to his seat. We followed the nurse into the examination room. While she weighed Paul, I told her how that man had made my day.
Motherhood is still a jungle sometimes, but now when I feel tired I remember the encouraging words of the old gentleman.
