When is a language not a language? When it"s a body language....OK, what a jolly clever remark - but isn"t it the case that 80%? 90% (or whatever factoid you like) of all communication we receive comes through the interpretation of subtle clues from other people"s bodies?Well ... actually ... is it ? It all depends what you mean by "communication" - and that depends crucially on what content is communicated, surely ?
