Right. So. And then we say, where is that force directed? Is it through a foot? Is it through a hip? Is it through an axial skeleton? How is it distributed? Is it distributed broadly? Or is it localized? So that's location. Okay. What direction is the force going? It's going up from the ground up. Is it going from the top down? Is it coming from the side? Is it internal? Is it external? You see, I can see location, direction, duration. How long am I applying this force? So initially, when I apply a force, say connective tissues might behave in a very stiff manner, but if I keep applying that force, the connective tissue behavior may change. So I might start in a stiff representation. And then because the duration of the force application is longer, now the connective tissue starts to yield. So that's a duration related change. That's a, like stress relaxation would be a representation of connective tissue behavior that changes with time. Cool. Frequency, like how many times is the force applied per unit of time? Okay. Is it a regular interval? Is it once every second? Or is it a random application over time? Cause the tissues will behave, as soon as I apply the force, the tissue behaves. If I release the force, the tissues will move back towards where they started, but how far into where they started does that tissue behave before I hit it again? Okay, so that's variability. Okay, and then we always talk about rate because it's an easy one to see. If I apply a force very, very quickly, the tissues might behave more stiff. If I apply it very slowly, they yield more effectively, right? So each one of those elements has an influence. They are all always there. They are all always there. It's just to what degree one might be represented more than the other or my intention.
