According to a study of 222,497 Australian adults 45 years or older, people who sit more than 11 hours a day have a 40% higher risk of dying in the next three years than people who sit less than four hours a day.

Healthy or sick, active or inactive, the more people sat, the more likely they were to die in the next three years. Physical activity did make a difference: the 40% higher death risk found when comparing people who sat the most to those who sat the least increased to 100% when comparing those who sat the most and exercised the least to those who sat the least and exercised the most. But while the death risk was much lower for anyone who exercised five hours a week or more, it still rose as these active people sat longer.

The results are part of the Sax Institute's 45 and Up Study, the largest ongoing study of healthy aging in the Southern Hemisphere.

So, stand up and live!
