Astonishing, the tensegrity. Its principle to this very day is largely hidden from public view. Even if, in fact, modern architecture largely depends on it. Tensegrity permits movement. Because of the tensegrity human bodies are at once pliable and stable.
There is something mysterious to movement. It gets more mysterious when small monitored motions and breath (more precisely breathing pauses) are combined. Something inexplicable occurs. Movement disorders dissolve. Pain vanishes...
Sit a-n-d move! Why not?
