This is a video clip on indicators of interest (IOIs). This video clip is part of a documentary (UK's Channel 4 - Body Talk "Sex") that reveals the body "tells" women use to indicate their interest in men. The host constructed a club-like environment and analyzed how the women responded to certain men. The women in the video used body language to reveal how they really felt about the men they were talking to.
