  Why do men die earlier than women?The latest research makes it known that the reason could be that men's hearts go into rapid decline when they reach middle age.

  The largest study of the effects of ageing on the heart has found that women's longevity may he linked to the fact that their hearts do not lose their pumping power with age.

  “We have found that the power of the male heart falls by 20~25 percent between 18 and 70 years of age,”said the head of the study,David Goldspink of Liverpool John Moores University in the UK.

  “Within the heart there are millions of cells that enable it to beat.Between the age of 20 and 70,one-third of those cells die and are not replaced in men,”said Goldspink.“This is part of the ageing process.”

  What surprises scientists is that the female heart sees very little loss of these cells.A healthy 70-year-old woman's heart could perform almost as well as a 20-year-old one's.

  “This gender difference might just explain why women live longer than men,”said Goldspink.

  They studied more than 250 healthy men and women between the ages of 18 and 80,focusing on healthy persons to remove the confusing influence of disease.

  The team has yet to find why ageing takes a greater loss on the male heart,said Goldspink.

  The good news is that men can improve the health of their heart with regular exercise.Goldspink stressed that women also need regular exercise to prevent their leg muscles becoming smaller and weaker as they age.

  Feeling tired lately? Has the doctor said he cannot find anything wrong with you? Perhaps he sent you to a hospital, but all the advanced equipment there shows that there is nothing wrong. Then consider this, you might be in a state of sub health (亚健康).

  Sub health, also called the third state or grey state, is explained as a border line state between health and disease. According to an investigation by the National Health Organization, over 45 percent of sub healthy people are middle-aged or elderly. The percentage is seven percent higher among people who work in management positions as well as students around exam time.

  Symptoms include a lack of energy, depression, slow reactions, insomnia(失眠), agitation(焦虑), and poor memory. Other symptoms include shortness of breath, sweating and aching in the waist and legs.

  The key to preventing and recovering from sub health, according to some medical experts, is to form good living habits, alternate work with rest, exercise regularly, and take part in open-air activities.

  As for meals, people are advised to eat less salt and sugar. They should also eat more fresh vegetables, fruits, fish because they are rich in nutritional elements——vitamins and trace elements——that are important to the body.

  Complaining(抱怨)about faulty goods or bad service is never easy. Most people dislike making a fuss(大惊小怪). But if something you have bought is faulty or does not do what is instructed for it, you are not asking for a favor to get it put right. It is the shopkeeper's responsibility(负责) to take the complaint seriously and to replace or repair a faulty article or put right poor service, because he is the person with whom you have entered into an agreement. The manufacturer may have a part to play but that comes later.

  Complaints should be made to a responsible person. Go back to the shop where you bought the goods, taking with you any receipt(发票)you may have. Ask to see the buyer in a large store. In a small store the assistant may also be the owner or you can complain directly. In a chain store ask to see the manager. If you telephone, ask the name of the person who handles your enquiry, otherwise you may never find out who dealt with the complaint later.

  Even the bravest person finds it difficult to stand up in group of people to complain, so if you do not want to do it in person, write a letter. Stick to the facts and keep a copy of what you write. At this stage you should give any receipt numbers, but you should not need to give receipts or other papers to prove you bought the article. If you are not satisfied with the answer you get, or if you do not get a reply, write to the managing director of the firm, shop, or organization. Be sure to keep copies of your own letters and any you receive.
