David. Even people who think they are sleeping enough would probably be better off with more rest.
　　22) The beginning of our sleep-deficit crisis can be traced to the invention of the light bulb a century ago. From diary entries and other personal accounts from the 18th and 19th centuries, sleep scientists have reached the conclusion that the average person used to sleep about 9.5 hours a night. “The best sleep habits once were forced on us, when we had nothing to do in the evening down on the farm, and it was dark”. By the 1950s and 1960s, that sleep schedule had been reduced dramatically, to between 7.5 and 8 hours, and most people had to wake to an alarm clock. “people cheat on their sleep, and they don’t even realize they’ve doing it.”Says Dr. David. “They think they’re okay because they can get by on 6.5 hours, when they really need 7.5, 8 or even more to feel ideally vigorous.”perhaps the most merciless robber of sleep, researchers say, is the complexity of the day.

　　Fast Food
　　Fast food is becoming more popular in China, especially among children and teenagers. Toaday, its certainly difficult to think of any other single thing that represents the fast pace of modern society as powerfully as fast food.
　　There are several reasons for its popularity. First, it is very convenient and saves a lot of time. The trends of modern society seem to all point to one ultimate goal--saving time.And fast food well serves this purpose. You just go into a fast food restaurant, order your food, and your food is ready in no time. You can either eat it there or take it away. Second, its popularity is also attributed to the clean and comfortable environment of fast food restaurants, the excellent service, and the guaranteed quality of food.However, in terms of nutrition, fast food is far from satisfactory.
