Not all think laughter is the best medicine, but it seems to help．So scientists carried on a new study of diabetes （糖尿病） patients who were given a good dose of humor for a year to prove it．
Researchers divide 20 high-risk diabetic patients into two groups．Both groups were given standard diabetes medicine．Group L viewed 30 minutes of humor of their choice, while Group C, the control group, did not．This went on for a year of treatments．
By two months into the study, the patients in the laughter group had lower level of the hormones epinephrine （腎上腺素）, considered to cause stress, which is known to be deadly．After the 12 months, HDL cholesterol rises 26 percent in Group L but only 3 percent in Group C．In another measure, C-reactive proteins, a maker of heart disease, drop 66 percent in the laughter group but only 26 percent in the control group．
“The best doctors believe that there is a physical good brought about by the positive emotion, happy laughter,” said study leader Lee Berk of Loma Linda University．And other research has found that humor makes us more hopeful．Still, more study is needed, Berk said．The research by Berk found that humor can bring about similar changes in body chemistry, which was proved in the new study．The research result will be presented this month at the meeting in the US．Research at the University of Maryland School of Medicine shows that laughter causes the inner lining of blood vessels to expand, increasing blood flow in a way thought to be healthy．
“Lifestyle choices have an important effect on health and these are choices which we and patients should pay attention to, rather than prevention and treatment,” Berk said in a statement this week．

All young people dream of travelling the world. They are restless and very eager to see new sights. However, they have little idea how they would really do it if given the chance. Because their knowledge of geography is quite limited, they seldom know much about the places they wish to visit or how they would get there.?
Already hundreds of thousands of Chinese student tourists are visiting these places-Wuyi, Lhasa, Lijiang, Dali, Vientiane and Phnom Penh. Indeed, these students will soon be the most travelled generation in China’s long history. The World Tourist Organization predicts that a quarter of a century from now the number of Chinese tourists going abroad will be twenty times what it is today. The largest percentage of these tourists will visit Southeast Asia. Not all Chinese who travel abroad will be tourists, however. More and more youths are deciding to volunteer their skills in this region; much like their peers in th-e Peace Corps and VSO.?
Critical thinking skills required include planning for a trip and solving problems after the trip has begun. The focus is on how to read an atlas (地圖集) to make travel plans and how to find ways of travelling. An atlas offers a wealth of information about geography and is one way to increase students’ awareness of their global environment. Use of an atlas especially addresses the needs of students with different visual and spatial (空間的) learning styles.
