Sleep is very important．A person who does not sleep dies faster than a person who does not eat．We spend about a third(1/3)of our lives in sleep．That's about 121 days a year!

　　How much sleep do we need?We are all different．A baby needs 16 hours of sleep every day．Children 6 to 12 years old need an average(平均)of 10 to 12 hours of sleep．Teenagers need 9 to 10 hours of sleep．An adult needs an average of 7 to 8 hours a night．There are some people who need only 3 hours of sleep．Others need 10 hours of sleep．After the age of 50, the average sleep time goes down to 6.5 hours a night．We need less sleep as we get older．

　　About one in three Americans has a problem with sleep．Many of these people cannot fall asleep．The name of this problem is insomnia．Some people say,“I didn't sleep all night．”But that's not really true．They may sleep lightly and wake up several times．In the morning, they only remember the times they were awake(醒着), so they think they were awake all night．

　　This is not a new problem．Many famous people in history had insomnia．Some of these people had special ideas to make them sleep．Benjamin Franklin had four beds．He moved from one to the other to fall asleep．Mark Twain had a different way．He lay on his side across the end of the bed!

　　A new TV series in England, Away from it all, has surprised everyone by becoming a huge success with young people across the country．Its success is surprising because the series is about the relaxing lifestyles of people who live in the country．There is none of the action that we usually see on TV today．There are also no stressful moments, busy offices or crowded cities．Away from it all is set in the peaceful English countryside and tells simple stories about people's kindness．

　　The director of the TV series says that its success is a sign of teenagers suffering from stress．They say that watching Away from it all helps teenagers forget about the pressures(压力)of exams and homework, and the troubles that fill the world today．They also say that it's a good sign of today's young people switching to(转到)happier TV series as it shows they would like a happier and healthier world．

　　Although the series'success might have a good side, many teachers and parents are worried, however．They say that some of their students and children are becoming couch potatoes(终日泡在电视机前的人)and are using Away from it all as an excuse for not completing homework．Some children have even refused to learn for exams because they say that they can only achieve personal happiness by avoiding(避免)stressful situations completely．

　　And what do the experts(专家)say?Paula Ray, a doctor of education, says that TV can influence children's lifestyles．But she says that if a child reacts strongly, it's likely that there are other reasons for his change in behaviour．She says that there is nothing wrong with watching Away from it all but suggests that parents should make sure their children know TV is not the same as real life．

　　Why do you think people who live in some hot countries eat very spicy(辛辣的)food?Is it because the spices make the food taste better?Is it just because their parents and grandparents and great-grandparents liked hot food, or is there some connection between spices and healthy food?

　　Researchers from Cornell University think that it is because spice plants have some important chemicals(化学物质)．These chemicals can kill bacteria(细菌)which spoil food．

　　“Most common spices can kill 75 to 100 percent of the bacteria in food,”explains one of the scientists．The bacteria grow more easily and spoil food more quickly at higher temperatures．For this reason, it is more difficult to keep food from spoiling in hot climates．

　　Do you like your food spicy?Your answer probably tells something about the country you come from．If you like spicy food, it is possible that hundreds of years ago, when there were no fridges, people in your country started using spices to keep the food from spoiling．The traditional spicy dishes helped those people to live longer, healthier lives．Today, in a time of fridges, the spices just make the food taste good．
