Chronic lower back pain cost the US $100 billion annually directly and two or three times that if you include indirect costs like loss of labour. However simple walking for about 1.5-2 hours daily reduced the risk of developing it by 23%. The cost reduction for society encouraging us to walk more and drive less are potentially huge (not even starting to count all the other health positives of walking). Why not start with encouraging the building of walkable mixed high density neighborhoods and towns that was the human norm for thousands of years? And make them walkable. We know from studies on campuses and theme parks that even Americans are happy to spend far more than 2 hours on their feet if they can be distracted by alluring or interesting surroundings.
