Liars

It´s been estimated that there are 111 different types of lie. Or did someone just make that up? Some good, some bad, and a few just plain evil. Individually, we each tell as many as 15 porkies a week (is that all?),and are on the receiving end of even more. And yet despite the fact lying is everywhere, few other human traits are so little understood. In this episode, Exposed attempts to unravel some of the mysteries surrounding this most powerful and seemingly instinctive human trait.
