New Health Care Prevention Strategy

So the White House announced it's new strategy for prevention in Health Care yesterday.  It is a very broad sweeping initiative that goes outside of the normal areas of health care to include transportation, housing, the workplace and the environment.  You can see an overview here and also download the entire plan.  From what I've ready if we can actually start getting people to think about health and the impacts their seemingly unrelated decisions can make on it, that would be fantastic.  I would never have thought to say 'I'm building a new housing community...are there sidewalks for exercise?  Is it close to shops?'  It makes you think.  There are so many little things we can all do to help with the big picture.  But can we change people enough to have an impact?  What do you think?
