Across cultures there are certain agreed upon standards of beauty. There are regional variations of course, but most of us would consider pic related to be physically attractive. My question is, why? The common explanation seems to be that beauty can be reduced to things like facial symmetry and a clear complexion, and that these qualities are positively correlated with health. This led our ancestors to evolve a preference for them. But I think there's far more to beauty than a list of characteristics. Thoughts?
