This is the one piece of bad news you shouldn't sit down for: Sitting for hours on end, every day, is bad for your health. Sitting at work is bad for you. Sitting after work is bad for you. Sitting is the new smoking, except that the furniture lobby probably isn't as powerful as the tobacco one.
A lot of research has appeared in the last few years as a testament to all that is unholy about our love of office chairs, La-Z Boys, couches and cushions. What's worse: Even a healthy amount of exercise can't save you.
If you work in an office setting, sitting is hard to avoid, unless you're an early adopter of the treadmill desk. You might laze around the house on your days off, but one study found that people spend more time sitting--and do less standing or walking--on work days compared to their leisure days.
You may have lost track of all of the ways that your office job can turn deadly. So as I sit hunched over in my rolling chair in a position that screams "live fast, die young," let's talk about what kind of damage all we, the over-sitters, are in for.
