"A small but growing collection of studies suggests that spending time in green spaces—gardens, parks, forests—can rejuvenate the mental resources that man-made environments deplete." Does this explain why it seems all great cities have large walkable parks near their core downtown areas and near any areas considered to be more livable? It isn't the park, per se, but perhaps the ability to find walkable conduits that can be ambled without concern for bodily harm. When I move to a new place one of the first things I do is locate the longest walkable circuit that does not involve busy intersections where waiting is required.
