The gray-haired lady can't wait to leave the building to search for her dad. Unless watched, she will walk in the streets in an effort to find her father, who died 30 years ago.

    Not all cases of Alzheimer's disease look like this, but Alzheimer's is a serious disease that is said to be the fourth or fifth leading cause of death for people over age 75. It is said that about three percent of the U.S. population over age 65 have Alzheimer's. In the early stages; people may exhibit short-term memory loss. Some may experience changes in personality, easy to be angry. As the disease progresses, patients might lose the ability to move and may be unable to speak or move at all. This progressive disease generally lasts 8 to 10 years before death occurs.

    While no one is certain what causes these changes in the brain's nerve fibers, their effect is certain. Alzheimer's destroys not only the patients, but also spouses（配偶）, friends and families.

    What should you do if you notice progressive memory loss in yourself or a loved one? Have the person examined by a doctor who is a specialist in the treatment of Alzheimer's disease. Though many reasons other than Alzheimer's disease may cause memory loss, its early diagnosis（诊断）and treatment may delay some of the most serious effects.

    What feeling will you likely experience if a loved one suffers from Alzheimer's disease? A person will often go through the various stages of sadness, shock, anger, and so on. If the spouse develops the disease, you may experience hurt and disappointment when he or she doesn't remember you are married.

    Life for the Alzheimer's patients and their loved ones will never be the same as the disease progresses, bringing a deep sorrow, loss and even anger towards God. No matter what feelings are present, facing them honestly will serve one better than burying them.

    Today, we know that the role of vitamins and minerals goes way beyond the prevention of deficiency diseases (维生素缺乏症) to actually preventing cancer and heart disease, the most fearsome killers of our time. With this knowledge has come the widespread call for nutritional supplementation (营养补充) — and a confusing group of vitamin, mineral, and supplements lining the supermarket shelves.

    Far from contributing to better health, however, nutritional supplements threaten to turn a scientific breakthrough into a nutritional disaster.

    Promoters of vitamins and minerals — especially vitamins A, C, and E— would have consumers believe that the little vitamin pill in the bottle is all they need for good health. Take your vitamins in the morning, and you're covered. It's okay to eat fast foods for the rest of the day or skip meals to achieve today's fashionably skinny look. But vitamins and minerals are only one part of the nutritional puzzle. A diet rich in fiber (纤维) and balanced in carbohydrates and protein is essential for good health. You can't get these things from a nutritional supplement. The focus on vitamin and mineral supplements may actually be robbing us of the full nutrition we seek.

    And no supplement can compare to the quality of nutrition found in natural sources. For example, our bodies turn carotenes (胡萝卜素) from plant foods into vitamin A. Many supplements contain a single carotene, but natural sources are rich in many different carotenes. Many supplements contain a form of vitamin E that is made from chemicals, when natural vitamin E is more readily absorbed and used by the body. And science is still discovering the wealth of nutrients in foods.

    You'd be hard-pressed to find a supplement as nutritionally comprehensive and powerful as a balanced diet. Even if you could, you'd pay much more than if you got the same nutritional value from natural sources.

    But perhaps the greatest danger presented by nutritional supplements comes from the very real risks presented by self-medication. Anyone can walk into the market and buy as many different supplements as desired. The reported benefits of high dosages of certain nutrients have led some people to believe that the more the better. Many take several vitamin and mineral supplements without regard to possible consequences.

    Surprising new research suggests that vitamin C pills may speed up hardening of the arteries, the underlying cause of heart attacks. Researchers said their findings support the recommendations of health organizations, which urge people to avoid high doses of supplements and to get their nutrients from food instead.

    As appealing as they're made to sound, nutritional supplements are danger in disguise. If you're looking for good health, don't look on the supplement shelves of your supermarket. Look in the produce section instead.

    A survey by an international temporary service agency found that U. S. managers believe that people with a sense of humour do better at their jobs, compared with those who have little or no sense of humour. In fact, about 96 percent of those surveyed said people with a sense of humour do better.

    The survey went on to point out that the results suggest that a sense of humour may help light-hearted employees keep their jobs during tough times. And, what's more, it may push them up the corporate ladder past their humourless colleagues. Why? It seems that those with a sense of humour are better communicators and better team players.

    Studies have shown that happy workers are more productive. In fact, a researcher at California State University found that humour could help the employees to release tension.

    Research done by psychologist Dr. Ashton Trice at Mary Baldwin College in Virginia showed that humour helps us think. When people feel stuck on important projects, they tend to feel angry or depressed.  According to Dr. Trice's research, taking time out to laugh can help us to get rid of negative feelings and allow us to return to a task or move on to another project unaffected by past defeat.

    If humour is really this important, then why don't we use it more often on the job? Most likely, the main reason is that many people are unaware of the positive effects of humour in the workplace. However, it is important to realize that some humour is not suitable for the workplace, and that it is often used at wrong times.

    E-mail systems at thousands of companies and government offices around the world were attacked by a virus(病毒)called “Melissa” that disguises(伪装)itself as an “important message from a friend. In spite of a weekend of warnings，more than 50 000 computers at about 100 places around the world have been attacked by the virus，computer security experts said on Monday.

    The virus began to show up last Friday and spread rapidly on Monday by making computers fire off dozens of infected(被传染的)e-mails. Although the virus causes no serious damage to a computer，its effect was far reaching.

    To make matters worse，a similar virus called “Papa” was discovered on Monday. Papa is programmed to send out even more infected e-mails than Melissa.

    The Melissa virus comes in the form of an e-mail，usually containing the subject line“Important Message”. It appears to be from a friend. The body of the e-mail message says，“Here is that document you asked for...,don't show it to anyone else.” Attached(附)to the message is a document file.

    Once the user opens that file，the virus digs into the user's address book and sends infected documents to the first 50 addresses. E-mails from the Papa virus include an attached spreadsheet(电子数据文件)file. When the user opens that file，the virus sends 60 infected e-mails.

    The reason why this is spreading so fast is that you are getting it from people you know. You should never open documents or attachments from people you don't know. People who get an unexpected e-mail with the “important message” subject line should delete it immediately and not open the message.

    Thirteen can be a challenging age. Not only did I have to adapt to my changing body, I also had to deal with my parents' bitter divorce, a new family and the upsetting move from my country home to a crowded town.

    When we moved, my beloved companion, a small brown pony had to be sold. I was heartbroken and terribly lonely. I couldn't eat or sleep and cried all the time. Finally, realizing how much I missed my pony, my father bought me another horse, Cowboy.

    Cowboy was without doubt the ugliest horse in the world. But I didn't care. I loved him beyond all reasons.

    I joined a riding club. When Cowboy and I entered the events where the horse was judged by appearance, we were quickly "shown the gate". I knew nothing could turn Cowboy into a beauty. My only chance to compete would be in the timed speed events. I chose the jumping race.

    For the whole next month we practiced running and jumping for hours in the hot sun and then I would walk Cowboy home, totally exhausted.

    All of our hard work didn't make me feel confident by the time the show came. One girl named Becky rode a big brown horse in the race events. She always won the blue ribbons. I sat at the gate and sweated all out while I watched Becky and her horse charge through the court and finish in first place.

    My turn finally came. At the signal, we dashed toward the first fence, jumped over it without trouble and raced on to the next one. Cowboy then flew over the second, third and fourth fences like a bird and I turned him toward the finish line.

    No cheers filled the air. The end of our run was met with surprised silence. Cowboy and I had beaten Becky and her fancy horse by two seconds.

    I gained much more than a blue ribbon that day. At thirteen, I realized that no matter what the odds, I'd always come out a winner if I wanted something badly enough to work for it. I can be the owner of my fate.

    If a family member blames you for something you have done, it is important to be careful about how you defend yourself. It is not a good idea to use ways that cause hurt, even if they would help you make a valid point. If you can think of an instance where the other person has done exactly what they accuse you of, for example, it would not be good manners to throw it in their face. You should only bring it up if you don't have a choice. Then, you should make sure that you do it respectfully.

    Even if a family member intentionally goes against reasonable wishes you may have, you should understand that people see even the most fundamental things in very different ways. Remember that people are different. If you consider any noise after midnight to be intolerable, for example, others may see it is completely acceptable. It can take them a great deal of time to change their behavior for a demand that they do not understand.

    Think about the family conflicts that you are worried about now. Check to see if your parents had similar problems. People who grow up with parents who fight unfairly often repeat the same behavior. Consider changing the unfair habits that you grew up with.

    Understand that memories tend to change. In long-standing family disputes, all parties involved tend to have completely different recollections of the original problem.

    Families are a curious concept—while family members often feel nothing but annoyed for one another, they will also often be there for them if they should ever be in serious trouble. When you feel resentment for someone, think about how far you would go for them if they happened to be in trouble. It could help soften you. Think about how you care for the other person.
