It turns out that TV really is bad for you... And it's bad even if you're exercising adequately!

Watching TV shortens life span, study finds

Watching television for hour upon hour obviously isn't the best way to spend leisure time -- inactivity has been linked to obesity and heart disease. But a new study quantifies TV viewing's effect on risk of death.

Researchers found that each hour a day spent watching TV was linked with an 18% greater risk of dying from cardiovascular disease, an 11% greater risk of all causes of death, and a 9% increased risk of death from cancer.


Researchers found a strong connection between TV hours and death from cardiovascular disease, not just among the overweight and obese, but among people who had a healthy weight and exercised.


"What we showed was that irrespective of a person's exercise level, sitting for four or more hours watching television was linked to a significant increase in risk of death compared to watching lower amounts of TV," said Dr. David Dunstan, lead author of the study and professor and head of the Physical Activity Laboratory at the Baker IDI Heart and Diabetes Institute in Victoria, Australia. "The message here is that in addition to promoting regular exercise, we also need to promote avoiding long periods of sitting, such as spending long hours in front of the computer screen."
Certainly this has no bearing on Internet use, or having a modern, sedentary job...
