According to a report by the British Heart Foundation (BHF), Britons spend two-and-a-half months a year sitting down.
(The study revealed that most Brits only walk half a mile a day and nearly half of women and a third of men are inactive. The average man is sitting for 78 days of the year - a fifth of his lifetime, and although women tend to me more on their feet than men we do far less exercise.)
