You live longer standing than.sitting, 5 years longer at least. You have less doctors visits, and a better brain. It gets exercised with all you encounter. Our minds and bodies are built to walk at least 5 miles, 8 kilometres, per day. Walking and working all day in a garden is just as good. Walking all day picking mushrooms in BC forests is excellent. Get out of your car, live longer, now isn't that smart. Now take your mind for a walk and get smart. The Garden Party, The Smartest Government of Canada, Declares : March 21st, World Walking Day.
