body language vid response

i learned that body language is very important in communications. in fact, 93% of communication is non-verbal. also, body language can affect whether or not a salesman can make the sale, as shown by an experiment with car salesmen. the salesman with a more confident smile and respect for the customer could have made an easier sale than the one with lower confidence in his voice and smile and an authority's posture. i had thought that chatting online was good enough for communicating, but now i know that it's not even half of it.
