Theatre of feelings

Theatre is the father of arts as they say, based on the fact that it marks the beginning of the appearance of art, then the language of the body is also the father of communication forces, as gestures, signals, and movements were the language of primitive humans before the emergence of spoken language. And although it has now appeared, the language of the body still exists but it is no longer an essential means of communication between people as it was before, but it has become a tool for revealing feelings. Through physical reactions, we can diagnose the emotional state of a person: are they happy or sad, comfortable or tense, honest or lying?
