Sitting. It is such an ubiquitous activity that we never really think about it in relation to our health.
Of course you probably already know that sitting hunched over in front of your computer for hours on end without taking a break leads to much physical discomfort, particularly cramped legs and backaches. But like most people, you probably figured that with a good chair and proper sitting position you can beat the problems that sitting brings. Unfortunately research shows that prolonged sitting, no matter how comfortable your position may be, still leads to serious health risks.
