>>42096054Posture is another way of saying structure, and when you look at advanced structures, you see many parts sustaining and suspending each to form a strong collective much greater than the sum of its parts. A cathedral for instance uses arches, domes and flying buttresses to sustain great weights in rock and stone that would be impossible by simply stacking them like a crude hut.
Now if you were to just stick a single flying buttress on the side of a mud hut, it woudn't elevate the structure at all. Pretty soon the buttress would fall over, and maybe even damage the hut in the process. Thus it is paramount to implement all the features in their arrangement complex together, where they form a self-sustaining whole.
Start with the head. Posture actually begins in many ways with the jaws, and the tongue inside the mouth. People with bad posture tend towards slackjawed mouthbreathing, and vice versa. It's easier to breath mouthways with a sloped posture - the first example of a compromise that must be overcome. Good posture requires the mouth to be closed, and supporting this, the tongue to be high up in the mouth, acting as a sort of supporting arch for the ceiling of the mouth.
Then, the neck and head. Neck, it shouldn't surprise anyway, needs to be upright, so the head is held high. The right feeling is when you can imagine a kind of invisible cord pulling on the back of your head, like you're suspended from a string. Difficult to do, but it becomes a lot easier with the jaw and tongue in position.
Then the shoulders. Prime shoulders are backwards, which pushes the chest and ribs forward and out, and creates a hollow in the back between the shoulder blades. The shoulders are maximally wide and strong in this position. Excruciating to attempt to maintain compared to mediocre slumped shoulders - but becomes easier when the head, jaws, and neck are all aligned.
Now the hips. If all of the above is in place, one may feel an overarching of the spine, which
