Here's a new warning from health experts: Sitting is deadly．Scientists are increasingly warning that sitting for prolonged periods — even if you also exercise regularly — could be   1  for your health．And it doesn't matter where the sitting takes place — at the office, at school, in the car or before a computer or TV — just the overall number of hours it   2   ．

       Research is preliminary, but several studies   3  people who spend most of their days sitting are more likely to be fat, have a heart attack or even die．

       In an editorial   4  this week in the British Journal of Sports Medicine, Elin Ekblom-Bak of the Swedish School of Sport and Health Sciences suggested that authorities rethink how they define   5  activity to highlight the dangers of sitting．

       While health officials have issued guidelines   6  minimum amounts of physical activity, they haven't suggested people try to limit how much time they spend in a seated  7  ．

       "After four hours of sitting, the body starts to send   8  signals," Ekblom-Bak said．She explained that genes regulating the amount of glucose and fat in the   9  start to shut down．

       Even for people who   10  , spending long stretches of time sitting at a desk is still harmful．Tim Armstrong, a physical activity expert at the World Health Organization, said people who exercise every day —   11  still spend a lot of time sitting — might get more benefit if that exercise were spread across the day,   12  in a single bout．

       That wasn't   13  news for Aytekin Can, 31, who works at a London financial company, and spends most of his days sitting   14  a computer．Several evenings a week, Can also teaches jiu jitsu, a Japanese martial art  15  wrestling, and also does Thai boxing．

       "I'm sure there are some detrimental   16  of staying still for too long, but I hope that being   17  when I can helps," he said．"I wouldn't want to think the sitting could be   18  dangerous．"

       Still, in a study published last year that tracked more than 17,000 Canadians for about a dozen years, researchers found people who sat   19  had a higher death risk, independently of whether or not they exercised．
