Is prolonged sitting bad for us? Chris Bowlby gets up from his desk to find out.
He meets researchers at Leicester University who think that simply standing up increases the metabolic rate and so reduces the risk of diabetes and cardiovascular disease.
The Department of Health is watching this and other similar research closely. If the causation is proved there could be serious implications for how we live and work.
But as Chris finds out, when he gives up his own chair, it's not easy being a stand-up guy in a world built for sitting.
