New research suggests that cutting daily sitting timeto less than three hours might extend your life by two years.

   “Humans were designed to move. But modernlifestyles and office jobs rarely encourage us to walk around,” says PeterKatzmarzyk, an expert at the University of Louisiana.

   “Sitting is common in our lives today. Wesit while we’re driving, eating and watching TV. And many of us sit for manyhours at work.” Katzmarzyk said.

   “We can’t throw away physical activity.It’s extremely important. We have 60 years of researchers showing us that.”Katzmarzyk said.

   Katzmarzyk and other researchers are tryingto discover how sitting all day affext our lifespans（寿命）.

   “This is a relatively new area ofstudy…Studies that have assessed the relationship between sitting and death ortelevision viewing and death have been very rare in the last four or five years,”said Katzmarzyk.

   Katzmarzyk and his colleagues analyzeddata from these studies, which involved almost 167,000 adults. Then they turnedto a government-run survey of Americans to find out exactly how much timepeople spend sitting and watching.

   Not only did the team find that U.S.citizens could live longer by sitting less, they found that cutting TV time toless than two hours a day could add an extra 1.4 years to their lives.

People who’ve spent half their waking lives sittingdown might well ask, “Is it ever too late to make a change?”

“We would say ‘No. It’s never too late.’ Physicalactivity is good for you at every age.” Katzmarzyk said.

Katzmarzyk says studying this problem has inspired histeam to make a few changes in their own lives. They recommend a few simplechanges: frequently getting up from your desk, taking walks at lunch time, andinstead of e-mailing colleagues, walking over to their offices and talkingface-to-face——all activities that can be enjoyable as well as life-extending.
