Body language is non-verbal communication.
It plays a vital role during the conversation.
Body language is composed of gestures (your facial expresssions), posture (the you sit & stand ), movement & eye contact.
Our body speaks more than our tongue. We express 60-70% through our body & 30-40% through our tongue.
