According to this article the average Briton spends up to 14 hours a day sitting down. It seems many people spend all day sitting down at work, then sit down on their commute home before going home to sit down on the sofa. For many people the only exercise they get is walking to their car. I guess I am a fairly typical example. I work on my laptop all day and tend to spend most of the evening watching the TV. I tend to only stand up when I cook in the evening and to water the garden. I do however, ensure I get at least 30 minutes of exercise a day whether it is going for a run or on the exercise bike, does that also count as sitting down?
