I mentioned that earlier. It's trial and error. Each set of humans has their own golden ratio. I'm sure that neanderthals had their own ratio of beauty in reference to their faces and so do we. In a billion years, so will those humans. It changes, here is no end to this system, only when that species of human becomes extinct.
This is what I mentioned earlier about primal beauty. I am not factoring in societal factors and such. I know all about the bodily ratio though, there is a separate ratio for that as well. Same as the face but on the body.
This is going to bother you, but I reject this ratio. Want to know why?
Because I simply refuse to. Hahahaha. There will be no ratio Agent Smith.
Not to mention plenty of examples in real life where things don't conform to the golden ratio, or even their own ratios. I feel like face desking right now. *sigh*

When I said we needed more science on this board, I didn't want pseudo science philosophers that try and bend the forum to their will.
