begins to add, uh, clarity

As you may know, I work for a trade publisher, and one of our lines is a series of manuals for professional electricians. The guy who writes the text is a professional electrician, but he isn't much of a writer. The classic example of his style, which I have kept all these years, I give you now:

Simply reading these words about an emergency power system that we have not seen or worked with does not sufficiently describe the importance of this type of system; but putting oneself in the position of being in the emergency room of a hospital having a severed artery sewn closed when a tornado destroys the electrical utility overhead pole-type distribution system and the room turns to blackness begins to add clarity.

Indeed it does, friend. Indeed it does.
