How Important is Physical Attractiveness and How Harmful is Female Vanity?

To distinguish: I want to discuss physical attractiveness as a more-or-less “objective” measure, as opposed to physical “attraction” between two people, which is entirely subjective and not always directly related to their objective attractiveness. There can be “chemistry” or attraction between unattractive people (sometimes nothing more than sex drive/libido or r-selected characteristics at play).
