One reason is that part of our brain looks at the world in terms of how it can interact with it -- for example grasping a handle, pushing a button, or stepping on a stair. There is a sense in which those things prompt those responses by being designed to be used. Stepping off a cliff is partly an extension of the impulse to grab and manipulate.
