Thinks s/he gets paid by the post
Years ago I read (somewhere) that the reason older folks "shuffle" is that when you are younger, your brain and eyes are able to adjust your vision so that when you walk, your vision doesn't seem to "bounce." The older you get, the less that happens. So older folks tend to smooth their gait so that their head doesn't move as much when they walk, keeping their visual picture more stable.
