How would your world be different without verbal language?

Without verbal communication life would still go on, just differently. We could still see how people feel, almost better than when we could talk. Language berriers would be non-existant which would make international relations far eaisier. However communication when it came to details, analysis, and technical materials would become vastly more difficult. Picture trying to read an instruction manual for a lawn mower, it could show a diagram of wht happens if you get you foot chopped up by the blades, but it couldn't tell you how to replace the oil. On the subject of reading, books would not exist, atleast not how when know them today. Books would have to consist of pictures, diagrams, and gists of emotion, that would make great complicated works of fiction useless and confusing.

The world in order to function in a modern, man to machine format would not exist, however when dealing with each other on a basic feelings level much more effecient and personal.
