  The amount of pressure exerted by the foot is not the same as the value
of the mass of an animal or its weight. For instance, a landing from a
jump produces several hundreds of pounds of pressure per square inch in a
145lb human such as myself, and this increased with height of the leap.
The greater the muscular effort of the step (as if pushing or pulling)
will increase the size and depth of the step and produce a greater
preserved estimate of pressure per square inch than if it were walking
smoothly. [For the lay people, of course.]

  Little steps are often the hardest to take.  We are too used to making leaps 
in the face of adversity, that a simple skip is so hard to do.  We should all 
learn to walk soft, walk small, see the world around us rather than zoom by it.
