Two views to health

I came across these two articles one right after another and find them interesting together. The Secret to a Healthy Body is a set of recommendations to health that essentially boil down to being active. Their specific suggestions include aerobic exercise, and stretching and balance exercises. Then Why New Yorkers Last Longer goes over research showing that New Yorker's live longer, and it attributes this to the fact that they walk more. New York, as a city, is organized such that it's easy to walk around the city rather than drive. This moderate exercise, walking, apparently is enough to give them an average longer life, and is enough to overcome all the pollution in that city.
