Communication is so fundamental to most of the things we do in our work as well as in our private lives. One of the most potent forms of communication is body language, the subtle – and sometimes not so subtle – ways in which our body gives off signals or ‘messages’. Sometimes body language reinforces what we are saying – for example, when we say yes and nod at the same time. At other times, body language undermines what we are saying – for example, when, in response to being asked how we are, we say: ‘I’m fine’, but the look on our face says we are anything but fine.
