Is blushing an only human trait? Do animals blush? Can an AI ever express emotion? 

The face is the chief seat of expression. In this episode, I discuss the biological and psychological process of blushing, based on The Expression of the Emotions in Man and Animals by Charles Darwin. I explore the different things that can trigger a blush, and the connection between blinking and blushing by analyzing In the Blink of an Eye by Walter Murch. I focus on self-awareness and how other people's opinions and the ways they perceive us can affect our self-image, and consequently, direct our behaviors and the decisions we make. What role does blushing play in terms of evolution and the development of consciousness? What is the conscience? I believe shame is not an emotion, but an action. How deep is your connection to yourself?
