What would the graph of the average distance from my feet to the ground (ignoring the angles of my feet) over the course of my life look like? I step over a threshold, the graph jumps slightly; I take off in an airplane, the graph jumps dramatically.
What would the two graphs of each foot look like?
What would the two, four-dimensionsal graphs (one graph for each foot; a dimension for time, and three for each of the possible angles relative to the center of the earth) look like? I wag my foot sitting in a chair, three dimensions wiggle; I walk around working in a restaurant, three dimensions flatten.
How about the single graph of their average?
What would the integral of these graphs be (the total area per 3 angles per lifetime of the distance from my feet to the ground)?
What would the average be? A single scalar whose value is the integral of one of the graphs (total distance) divided by their domain (a lifetime); or, per angle of my feet, the total distance my feet were from the ground over the course of my lifetime.
What would the total average graph be: this integral scalar divided by the average of the angles of my two feet? This is the integer of posture and of elevation.
What would all these graphs look like relative to sea level? These are the quantities of posture and of evolution. Time, ever the independent variable, would become dependent, read backwards from the infinite detail of water flow (or again, of the movement of dust, sand, and concrete).
Add a fifth (and sixth, seventh, eighth?) dimension. Direction of blood flow. Blood flow would slow in accordance with time, near the end.
