A lot of the people Ken's come down to our addiction to car dependent infrastructure. If, instead of 15 feet walks to the car we had 15 minutes of walking to a transit stop, that alone would go a long ways to improving health.

Somebody who wants to live a healthy lifestyle has to actively fight against infrastructure that requires large amounts of sitting in a car to accomplish all daily tasks. A walkable of bikeable neighborhood changes everything for the worse, making it harder to get exercise and harder to meet people and build social connections.
