There's so much more you could do, if you wanted to take Active Design to its most absurd conclusion! (For example, you could lock doors with huge decorative keys that weighed many pounds each, so unlocking them would be a weight-lifting exercise.)

But we had moved so far in the opposite direction, with locations that are literally unwalkable—neighborhoods separated from grocery stores by freeways, overpasses with no sidewalks—and many others that are so unwelcoming as to be unwalkable as a practical matter, where the buildings turn a blank wall to one side of the sidewalk while high-speed traffic zips past on the other side.

We can go a long way before we reach the absurd conclusion.
