Shorter people are better for the environment (consume less resources), develop fewer health problems, and live longer than tall people, generally speaking. Great height is really only advantageous socially - I mean ever since guns and other weapons were brought into the equation, the physical advantages of being tall only really apply in organized sports. But the social advantage that height brings is huge, and I think most people would take the disadvantageous of being tall if they could have the height since the benefits are primarily social, and humans are social creatures.
