Is working standing up good for health?
Standing up three hours a day, five days a week for a year, would be the equivalent of "running ten marathons" according to UK health experts.
Dr Mike Loosemore, head of Exercise Medicine at University College Hospital, told the Today programme's Justin Webb that small amounts of regular physical activity, like standing up and walking short distances, can improve health in the long term and reduce risks of high blood pressure, heart disease and even cancer.
First broadcast on BBC Radio 4's Today programme on Friday 20 June.
