The Art of Modularity Is Very Powerful

Even a spark plug will have multiple sub components in it. Machinery usually has multiple layers of sub components within it. This allows sort of modularity to the design, such that if one component breaks, the entire thing doesn't break down. You see this kind of modularity i, i mean, it's very apparent these days with the human body. We do surgeries that replace organs all the time. These days you can do a face transplant these days. You can replace someone's heart, or a valve in the heart with an artificial valve. You can even replace an amputated leg. Ou can sew parts of the body back on.
