The connection between hoarding and ballet

It’s not obvious but the connection is that some people define pathways of movement through their physical world, particularly through the physical world they control. A hoarder loads up his or her place to make what appears to be a mess but which is organized at a minimum to direct movement down physical pathways that are constrained by the physical impediments which represent the mental areas filled. This is very much a sticks and shapes metaphor. The ballet dancer moves through choreography, a set of defined movements which the dancer must practice to learn so the physical pathways draw on all that learning plus the various references to movement and meaning contained in the choreography. A hoarder does the same thing. All collectors do, and dancing is a collection of physical capacities.
