We think with our minds and act on what we think.
If we flip this view, the world looks different.
James Gibson called the nature of our interaction with our environment affordance.
For example, sitting in a chair is also an interaction between the whole body and the chair.
We can think and act because there is affordance between us and things.
Posture is the force that brings out affordance.
Sit still, breathe out.
It makes you calm.
