Can you spot someone who is in the swinging lifestyle?

When you look across a crowded room, what can you insinuate about the people you see? At a work event, you can often tell who are the power players in the room — those who are clearly at the centre of group conversations, almost ‘holding court’, as others listen, feeling lucky to be part of the conversation. Similarly, at social events you can usually get a pretty good read on who is fun to be around, who is a little shy and reserved, and maybe even who is putting out a vibe that they may want to meet someone.
