Every hour spent in watching TV, DVDs and videos as an adult reduces life expectancy by almost 22 minutes, a study suggests. And viewing TV for an average of six hours a day can cut short your life by five years.
The research claims that a sedentary(久坐的) lifestyle is as bad for health as smoking and obesity, because of the dangers caused by inactivity and the greater opportunities it offers for unhealthy eating.
The academics conducting the study set out to calculate the overall risk to life expectancy from watching television. Their research involved more than 11,000 people over the age of 25.
Writing in the British Journal of Sports Medicine, they concluded. "TV viewing time may be associated with a loss of life, which is similar to other major chronic disease risk factors such as physical inactivity and obesity."
The researchers, from the University of Queensland, used information from the Australian Diabetes, Obesity and Lifestyle Study, together with population and death rate data.
But they said: "Although we used Australian data, the effects in other industrialized and developing countries are likely to be similar, considering the large amounts of time spent watching TV and similarities in disease patterns." In the United Kingdom, the average amount of time spent watching TV is four hours a day, compared with five hours in the United States.
Earlier this year, a separate study suggested the risk of developing type 2 diabetes and heart disease, or dying early, rises by as much as 20 percent after just two hours a day in front of the box.
England's Chief Medical Officer, Sally Davies, said: "Physical activity offers huge benefits and these studies back what we already know - that a sedentary lifestyle carries additional risks. We hope these studies will help more people realize that there are many ways to get exercise."

阳光课堂课时作业系列答案If you live in America in the 21st century you'll probably have to listen to a lot of people tell you how busy they are. It's become the default response when you ask anyone how they are doing:"Busy!""Crazy busy!".It is,pretty obviously,a boast disguised as a complaint. And the common response is a kind of congratulation:"That's a good problem to have,"or"Better than the opposite."
Notice it isn't generally people pulling back-to-back shifts in the ICU or commuting by bus to three minimum-wage jobs who tell you how busy they are.What those people are is not busy but tired.Exhausted!Dead on their feet.It's almost always people whose busyness is purely self-imposed:work and obligations they've taken on voluntarily,classes and activities they've "encouraged" their kids to participate in.They're busy because of their own ambition or drive or anxiety,because they're addicted to busyness and dread that they might have to face in its absence.
Almost everyone I know is busy. They feel anxious and guilty when they aren't either working or doing something to promote their work.It's something they have chosen.Busyness serves as a kind of existential reassurance(令人安心的保证），a measure against emptiness,obviously your life cannot possibly be silly or tiny or meaningless if you are so busy,completely booked,in demand every hour of the day.
Idleness is not just a vacation.It is as necessary to the brain as vitamin D is to the body,and deprived of it we suffer a mental affliction as ugly as rickets.The space and quiet that idleness provides is a necessary condition for standing back from life and seeing it whole,for making unexpected connections and waiting for the wild summer lightning strikes of inspiration."Idle dreaming is often the essence of what we do,"wrote Thomas Pynchon.Archimedes' "Eureka"in the bath, Newton's apple :history is full of stories of inspirations that come in idle moments.

Open 2 pm to 10 pm.The bar-tailed godwit （斑尾鷸）has just broken its own record for the world’s longest non-stop flight, including humans in planes, according to a report made by Lund University Press. The bird can fly non-stop for eight days, while the most impressive man-made airplane can only remain in the sky for 82 hours without a stop.
The bar-tailed godwit’s journey, from Alaska to New Zealand, covers over 6,835 miles. It completes this trip twice a year, in autumn going to New Zealand, and in spring back to Alaska. The tireless bird ends the trip without stopping once for food or rest. All other birds can only finish trips that are twice as short as what the bar-tailed godwit travels.
One reason for the bar-tailed godwit’s success is that it has made the best use of its fuel, which is only 0.41 percent of its body weight over each hour of any given long flight. Hedenstrom, a professor from Lund University, says, “This figure is extremely low compared with other birds.” The bird also has a special body shape that helps it fly easily. It stores body fat and protein to manage its trips. It also travels fast, compared to other birds and animals.
Many questions remain about this bird record holder that never gets lost in the air. Researchers wonder whether it has an inside compass (指南针) that helps it to know the direction. Please watch how beautiful bar-tailed godwits look as they come in for a landing, along with other birds.
