Standing is harder than moving.

In order to recognize small changes in effort, the effort itself must first be reduced. More delicate and improved control of movement is possible only through the increase of sensitivity, through a greater ability to sense differences.

No matter how closely we look, it is difficult to find a mental act that can take place without the support of some physical function.
