Collaboration is a key to success! Structure is an art of body. The body has a backbone in center. The backbone resists gravity force and lateral forces such as wind and earthquake.
That is why we call it core. The core is not visible but hold all organs, fresh, muscle, even hair.
Invisible doesn't mean it doesn't suffer. It may cry behind the screen.
Structure is our backbone. The backbone is not eternal.
