We treat desire as a problem to be solved, address what desire is for and focus on that something and how to acquire it rather than on the nature and the sensation of desire, though often it is the desire between us and the object of desire that fills the space in between with the blue of longing.

Perhaps walking is best imagined as an 'indicator species,' to use an ecologist's term. An indicator species signifies the health of an ecosystem, and its endangerment or diminishment can be an early warning sign of systemic trouble.
