 Right there on his forehead, we, when we are expressive a lot and we express ourselves often, they kind of etch themselves onto our face. My forehead has got little wrinkles on it, but you can't see on zoom. But there's a lack of conversational interaction and response here. His forehead is baby smooth right here, which means he's spent a lifetime not performing an eyebrow flash, which we commonly do when we greet people. These are social skills. So just looking at the lack of wrinkles on the face can give us some indicator of who we might be speaking with in this situation.
