Confession: I’ve become desk-bound. It's no fault but my own, but I've turned into a right desk potato. Lately, I’ve even started lunching al desko. And I’m not alone, as eight out of 10 office workers admit they barely leave their desks during the working day. The only time we stretch out our legs is when we take the few steps to and from the loo, or the kitchen when it’s our turn to make the tea round. But health experts agree that endless hours of sitting are playing havoc with our health, weight and state of mind, putting us at greater risk of lifestyle diseases such as type 2 diabetes.
