It is widely understood that one of the huge differences in lifestyle between modern people and their ancestors is that we sit a lot more and walk a lot less. This sitting, particularly sitting for long periods in chairs, and particularly in front of desks with our head and shoulders hunched forward, has contributed to a lot of discomfort and injury.
