    Fun fact I am right-handed, however with a computer mouse, I've always been ambidextrous, but better/dominant left-handed with them, but only with a computer mouse, everything else I'm right handed.

    We have two hemispheres for your efficiency explanation but also to provide spectrums for all the potential energy and cross communication between polarities of mirror images as this is how the depth of mirrors is determined on what plane of depth we are. Vertically divided and blind, we mirror along the vertical line. We are two people complex genetic at best, and so we reflect metaphorical creation.
