Turns out that sitting in a chair staring at a computer all day is terrible for you.According to a study by BMJ Open, reducing “excessive sitting” to under 3 hours a day would increase US life expectancy by 2 years. A doctor recently told the LA Times that “sitting is the new smoking.”And if that doesn’t faze you, how about a March 2012 study in the Archives of Internal Medicine with 200,000 Australian people found that regardless of sex, age and weight, sitting puts you at a higher risk of death from all causes.Unfortunately, unless you like standing at your desk like a Googler, you don’t really have much of an option.
