The hard truth is we are wired for Evolutionary Biology. What we call beautiful are core indicators of reproductive health and resource production health. Women’s ‘Rule of Sixes’ (Six Foot, Six Pack, Six Figures) is founded on evolutionary biology as they all indicate his potential for resource creation and protection as she considers him as a mate. Likewise men’s Tripple-F rule, (Fit, Feminine, and Friendly) taps into the same physiology and psychology.
