I have an "innie" bellybutton. A good question is do your earlobes join your face or is there a gap between the earlobe and the the side of your face/neck area?.
I was told that having pendulous, separated from the head, earlobes is a sign of "blue blood".
Since I heard that I've looked out for them. There is a guy at work who's lobes hang from his ears and don't attach to his face at all. He is quite posh, from an old family etc.
Trouble is, once you know this you find yourself staring inappropriately at people's ears.
