Office workers are putting their health at risk by spending too much of the day seated, according to a survey from the British Heart Foundation.
It found that the average person sat for almost all of the nine hours spent in the office.
Heart disease, type 2 diabetes, cancers and poor mental health have all been linked to sedentary behaviour.
