Does stress cause gray hair? Many people believe that tension and stress can cause your hair to lose its color．In fact，it is an old wives tale that being upset all the time can result in premature graying．Here is a closer look at this situation and why some believe that this old wives tale could be true．
As one ages，the hairs on the head also age．In fact，just about everything on the human body begins to show signs of wear and tear after a while．The joints wear and become stiff and skin wears and becomes wrinkled．Hairs on the head grow and eventually die．They are replaced，but in the process something else happens．
When new hairs are replaced，the color or pigment(色素)is also added to them．However，as one ages，this pigment becomes less and less available．At first，hairs will have a limited amount of pigment and they will appear to be grayish in color．In time，they will lose all of their pigment and will be white．Many things are known to cause graying．and genetics is a very powerful factor．If one of your parents turns gray at an early age，there is a good chance that you will too．Some people begin the graying process in high school，while others may be over the age of forty．
Constant worry and tension can have many harmful effects on the human body．It is a known fact that stressful times can cause one to suffer hair loss．It would make sense that if it can cause these problems，perhaps it also may contribute to graying．However，there is no sound evidence to support this．
On the other hand，many medical professionals believe that there may be a link：between graying and a constant state of anxiety or tension．Does stress cause gray hair? There is no scientific evidence to support the theory，but it is best to avoid stressful situations．

Have you ever intended to be fully absorbed in your work but found yourself distracted (走神) by e-mail, the Internet and other things throughout the day? According to the survey made by a famous university in the USA, most people have the experience.
“People often lose their concentration when they are bored, of course, but also when they are engaged in challenging tasks,” says Peter Bregman, the head of the survey. “They sometimes have a feeling to escape from what’s difficult or boring, so they jump out,” he says. The part of the brain devoted to attention is connected to the brain’s emotional center. Any strong emotion —quarrels with colleagues, problems at home —can interrupt our attention. Studies over the last decade have shown that too much work to do at a time can easily lead to distraction.
Refocusing is hard for many people. Robert Epstein suggests the following, “Stop and listen to some soft music for a few minutes. Find a good friend or a teacher and say out your matter on your mind. Go for a short walk or take a deep breath, where you breathe in deeply, count to five slowly, hold it and breathe out very slowly. This can blow out all the tension and the unwanted in your mind to restore your focus.”
Take more control by structuring your time and becoming more aware of your behaviors.“Setting the phone alarm to go off every hour is my way of creating awareness,”Mr. Bregman says.“You have to inform yourself that you’ve lost focus in order to do something about it.” Starting the day with a to-do list is also important, such as when to eat, when to go to the gym or take a walk. But if it’s overly ambitious, you will put yourself in a state of anxiety, which makes it hard for the brain to concentrate. “Choosing three or four things as your priority (优先) for the day allows your brain to settle down and focus,” he says.

The sound of the rain hitting the windows wakes me up and it sounds just exactly as it did 15 years ago, which reminded me of my girlhood.
It was my second day of school and it was raining heavily. I could not resist the habit I had at home, so I fell asleep right at my desk. I woke up to find myself not in the classroom but carried on Dad’s back. We were halfway home. It was the last time I felt close to him.
After that, he never carried me or hugged me as other fathers did to their children. I was not bothered much by this thought. I was proud of it, for I felt independent and “grown up.” However, there were times when I felt depressed by not having sought comfort from him.
One day, I was writing Chinese characters as homework. I hated doing this more than anything. Dad came and stood behind me for a moment, watching me scratching the paper. Then he said, “This kind of writing needs patience. Your writing is not strong enough. Press harder.”
I follow his advice for the next two words, but as I could see little improvement, I followed my own method----the fast way. His advice did not improve my writing but our relationship. As I grew older, I found out that he had finished his schooling in Grade 6, which was the highest grade in the town then, so he was considered to be a scholar. People used to ask him to write something to put on the walls, but he never felt very useful.
He often said to me, “As you can see, this family is going to count on you. We are useless to improve you anything for your future.You have to get an education to change the life for yourself.” As a result of his expectation, I have made it through high school and through college.

Many people believe they are supposed to drink eight glasses of water a day, or about two liters. Why? Because that is the amount of water they have been told all their life. But a recent report offers some different advice. Experts suggest people should obey their bodies: they should drink as much water as they feel like drinking.
The report says most healthy people meet their daily needs for liquid by letting thirst be their guide. The report is from the Institute of Medicine, which provides scientific and technical advice to the government and the public. The report contains some general suggestions. It says women should get about 2.7 liters of water daily and men about 3.7 liters. But wait–in each case, that is more than eight glasses.
There is one important difference. The report does not tell people how many glasses of water are needed to meet these guidelines. This is because the daily water requirement can include the water content in foods.
As you might expect, the Institute of Medicine says people need to drink more water when they are physically active. The same is true of those who live in hot climates. Depending on heat and activity, people could need twice as much water as others do.
All this, however, does not answer one question. No one seems sure why people have the idea that good health requires eight glasses of water daily. It may have started with a misunderstanding.
