Sitting in front of the television may be relaxing，but spending too much time in front of it may take years off your life.Watching television less may help you live a much longer life.

Australian researchers studied more than 11，000 people over the age of 25.Their study showed that if people watched TV for six hours a day，they lived about 4.8 years less than those who didn't watch any television.Also，people who are over the age of 25 lose 22 minutes of life for every hour of TV that they watch.

Sitting in front of the television isn't healthy.The more TV you watch，the less exercise you'll get.And the less exercise you get，the more likely it is that you'll get sick.

Lennert Veerman，the researcher who led the study，says watching too much TV will be bad for people's life expectancies(预期寿命)，even for people who have a good diet.He thinks it's necessary for doctors to start asking their patients about how much TV they watch，as it can be an indicator(指标)of someone's overall health.

Therefore，Veerman has called on people to turn off their TVs and get off the sofa to get some exercise.“Exercise is good，” he said.“Even light activity is good for health.”
