Until you work directly with it, or work with people who work directly with it, there are forms of decomposition that just remain hidden until something or someone brings it to your attention. Let's say, for example, the effects of wet soil on plant leaves, wood beams, or shovel blades. It is hard on all of them. It spreads disease and rot on the plants, it rots and decomposes the lumber, and it breaks down the shovel blades.
These oversights can be embarrassing, but how could it be otherwise? Some signals are just too insulated the further you are from them. And you learn of them through hard experience, or by someone who has learned through hard experience telling you directly about it.
And sometimes you just bang an elbow on something. After all, the elbow is not the centralized thing doing the coordinating. But getting more in touch with your elbow does help to cut down on the banging.
