Life Expectancy
A greater number of people are now hitting the eighty-year mark than ten years ago. In fact, the life expectancy of the average human has gone up considerably and is rising still. This encouraging phenomenon is the result of many factors. Advancement in technology, improved quality of life, and people’s rising awareness about health are all conducive to prolonged lives. Scientific and medical breakthroughs ensure that patients receive proper and timely treatment. As people learn more about the human body, medical institutions and services become better equipped to tackle various health problems. Diseases such as cancer, which used to result almost inevitably in death, are now largely curable, provided they are diagnosed at an early stage. Tuberculosis and cholera now cause fewer deaths than in the past. Thanks to new drugs, therapies and vaccines, fewer people fail victim to the diseases that once threatened human lives. With advanced facilities, infectious diseases are strictly monitored and controlled. The rate of mortality no longer reaches an alarming height even aider the outbreak of an epidemic. In addition to better health care, the improved quality of life definitely contributes to the longer life expectancy. People engage in less hazardous occupations. As far as food is concerned, they don’t simply enjoy the taste, but also good nutrition. Mineral water, fruit juice rich in vitamins, varieties of vegetables and dairy products are no longer luxuries. The general hygiene standard has gone up considerably as well. It is little surprising to find airy and sunny homes with shining kitchen sinks and shower heads.

THIS CONTRASTS SHARPLY WITH THE PAST WHEN MANY PREFERRED TO WORK OFF THE AILMENTS OR SIMPLY TOOK SOME DRUGS WITHOUT MUCH SERIOUS THOUGHT. THEY HAVE LEARNED TO MAINTAIN A SUITABLE AMOUNT OF WORKLOAD AND TAKE BREAKS AND PHYSICAL EXERCISES IN ORDER TO AVOID STRESS-RELATED DISEASES, SUCH AS HIGH BLOOD PRESSURE AND HEART ATTACK. A BALANCED DIET, SOMETHING THAT ONLY ELITE CIRCLES WOULD CARE ABOUT YEARS AGO, HAS BECOME A BIG CONCERN FOR THE GENERAL PUBLIC.

People are willing to take regular checkups and seek professional counseling when suffering from physical discomfort. This contrasts sharply with the past when many preferred to work off the ailments or simply took some drugs without much serious thought. They have learned to maintain a suitable amount of workload and take breaks and physical exercises in order to avoid stress-related diseases, such as high blood pressure and heart attack. A balanced diet, something that only elite circles would care about years ago, has become a big concern for the general public. 现在公众的健康意识也提高了。人们身体不舒服时，愿意做定期检查，寻求专业咨询。这和过去人们形成了鲜明的对比，过去人们生病会在不加思考的情况下自己挨过去，或者简单吃一些药。人们已经学会在保持一定的工作量的同时注意休息，加强锻炼，以此来避免因压力引起的疾病，比如高血压和心脏病。像饮食均衡这种几年之前只有精英才关心的事情，现在已在大众中普及。
