What constitutes beauty?
Among cultures and through history, standards of beauty have changed considerably. At certain times, stoutness was a symbol of wealth and influence and thus was considered attractive.
At other times, hardy physical fitness was the gold-standard. Different variations of skin tone, facial hair (men), breast size (women), eye color, hair texture, color, and style have all experienced wide swings in their perceived
attractiveness at different points in history and in different places.
When it comes to physical attraction, cultural forces far outweigh biological ones, but there are a couple of features that seem to cut through the cultural conditioning and are seen as universally attractive.
