Cooking Off Fumes Cause TumorThe leading cause of lung cancer among women in the city was cooking oil fumes while men are more likely to develop the disease from smoking, said medical experts after a five-year research study.Doctors announced the results yesterday with analysis on some new tendencies in lung cancer. They said patients are younger, especially women.According to the Shanghai Tumor Research Institute, more local residents die of lung cancer in the city than anything else. Following breast cancer, it has the second-highest incidence rate."An unhealthy lifestyle is a very important reason for lung cancer," said Dr. He Yumin from Shanghai Minshen Traditional Chinese Medicine Tumor Diagnosis and Treatment Center.He followed 2,276 lung cancer patients for five years. Among them, 1,483 were male.Smoking causes 70 percent of cases among men while only 18 percent of female patients developed cancer from smoking or inhaling second-hand smoke, according to the report.However, more than 60 percent of women with the disease had long-term, close contact with strong oil fumes from cooking and complained about irritated eyes and throat.About 32 percent of women fried foods in boiling oil in unventilated kitchens and about 25 percent of women"s bedrooms were adjacent to the kitchen.However, local women were surprised to learn cooking oil fumes could lead to cancer. Some claimed they may change food preparation methods."Unless my family and I don"t eat at home every day, I must stay in the kitchen to cook," said Xu Li, a 45-year-old local woman. "I know the fumes are bad for the skin, but it is the first time I heard that it can result in lung cancer. I have already started frying less."Doctors said women"s lung cancer had few links to personal health and physical condition, but was closely related to family cancer history, unhealthy dietary habits and weak immune systems.Other experts agreed with He."Smoking is by far the biggest cause of lung cancer for men," said Dr. Tan Binyong, honorary president of the Respiratory Disease Institute at Fudan University"s Medical College. "It"s true that second-hand smoke and cooking fumes are the main causes among women."He"s research also warned people not to stand near of stalls selling fried foods due to the poor quality of oils used.The chance of catching lung cancer is three times higher if exposed to the fume for a long time, experts said. Poor personal health and physical condition is the main reason for women"s lung cancer.

The majority of housewives in Shanghai have realized the harm cooking oil fumes do to their skin.
Modern scientists divide the process of dying into two phases—clinical or temporary death and biological death. Clinical death occurs when the vital organs, such as the heart or lungs, have ceased to function, but have not suffered permanent damage. The organism can still be revived (复活). Biological death occurs when changes in the organism lead to the "breaking up" of vital cells and tissues. Death is then unchangeable and final.Scientists have been seeking a way to prolong the period of clinical death so that the organism can remain alive before biological death occurs. The best method developed so far involves cooling of the organism, combined with narcotic(麻醉的) sleep. By slowing down the body"s metabolism (新陈代谢),cooling delays the processes leading to biological death.To illustrate how this works, scientists performed an experiment on a six-year-old female monkey called Keta. The scientist put Keta to sleep with a narcotic. Then they surrounded her body with ice bags and began checking her body temperature. When it had dropped to 28 degrees the scientists began draining blood from an artery (动脉). The monkey"s blood pressure decreased and an hour later both the heart and respiration stopped: clinical death set in. For twenty minutes Keta remained in this state. Her temperature dropped to 22 degrees. At this point the scientists pumped blood into an artery in the direction of the heart and started artificial respiration. After two minutes Keta"s heart became active once more. After fifteen minutes, spontaneous (自然产生的) respiration began, and after four hours Keta opened her eyes and lifted her head. After six hours, when the scientists tried to give her a penicillin injection, Keta seized the syringe (注射器) and ran with it around the room. Her behavior differed little from that of a healthy animal. How long was Keta in the state of clinical death
Look after Your VoiceOften speakers at a meeting experience dry mouths and ask for a glass of water. You can solve the problem by activating the saliva in your mouth. First gently bite the edges of your tongue with your teeth. Or press your entire tongue to the bottom of your mouth and hold it there until the saliva flows. Or you can imagine that you are slicing a big juicy lemon and sucking the juice.Before you begin your talk, be kind to your voice. Avoid milk or creamy drinks which coat your throat. Keep your throat wet by drinking a little sweetened warm tea or diluted fruit juice.If you sense that you are losing your voice, stop talking completely. Save your voice for your speech. You may feel foolish using paper to write notes, but the best thing you can do is to rest your voice. If you need to see a doctor, perhaps you can get some advice from a professional singer. In the meantime, do not even talk in a low voice.What about drinking alcohol to wet your throat I advise you not to touch alcohol before speaking. The problem with alcohol is that one drink gives you a little confidence. The second drink gives you even more confidence. Finally you will feel all-powerful and you will feel you can do everything, but in fact your brain and your mouth do not work together properly. Save the alcohol until after you finish speaking.Perhaps you want to accept the advice, but you may wonder if you can ever change the habits of a lifetime. Of course you can. Goethe, who lived before indoor skating rinks or swimming pools, said," We learn to skate in the summer and swim in the winter. " Take this message to heart and give yourself time to develop your new habits. If you are willing to change, you will soon be able to say that you will never forget these techniques because they became a part of your body. Why does the writer cite Goethe"s advice
SleepwalkingNot all sleep is the same every night. We experience some deep, quiet sleep and some active sleep, which is when dreams happen. You might think sleepwalking would happen during active sleep, but a person isn"t physically active during active sleep. Sleepwalking usually happens in the first few hours of sleep in the stage called slow-wave or deep sleep.Not all sleepwalkers actually walk. Some simply sit up or stand in bed or act like they"re awake when in fact, they"re asleep! Most, however, do get up and move around for a few seconds or for as long as half an hour.Sleepwalkers" eyes are open, but they don"t see the same way they do when they"re awake and often think they"re in different rooms of the house or different places altogether. Sleepwalkers tend to go back to bed on their own and they won"t remember it in the morning.Researchers estimate that about 15% of kids sleepwalk regularly. Sleepwalking may run in families (在家族中世代相传) and sometimes occurs when a person is sick, has a fever, is not getting enough sleep, or is stressed (紧张) .If sleepwalking occurs frequently, every night or so, it"s a good idea for your morn or dad to take you to see your doctor. But occasional sleepwalking generally isn"t something to worry about, although it may look funny or even scary (骇人的) for the people who see a sleepwalker in action.Although occasional sleepwalking isn"t a big deal, it"s important, of course, that the person is kept safe. Precautions (预防措) should be taken so the person is less likely to fall down, run into something, or walk out the front door while sleepwalking. Measures should be taken to ______.
