The article reported that a study of nearly 9,000 Australians found for each additional hour of television a person watched per day,the risk of dying rose by 11 percent.Another study followed the health of 123,000 Americans.The death rate for men who spent six hours or more per day sitting was about 20 percent higher than for men who sat for three hours or less.The death rate for women who sat for more than six hours a day was about 40 percent higher.In other words,sitting is killing us.So what can we do about it?Health experts suggest we break up those many hours spent sitting with more hours spent standing.

　　The BBC and the University of Chester conducted a simple experiment with a small group of 10 volunteers who usually spent most of the day sitting.They were asked to stand for at least three hours a day.The researchers measured by day when the volunteers stood,and when they sat around.When they looked at the data there were some striking differences.Standing burned more calories.

　　John Buckley,a member of the research team,said that although doing exercise offers many proven benefits,our bodies also need the constant increase in muscle activity that standing provides.Small adjustments,like standing while talking on the phone,going over to talk to a colleague rather than sending an e-mail,or simply taking the stairs instead of the lift,will help.

　　Title Stand up for 1. 

　　Fact It is 2.　 for many people to sit eleven hours a day.
