What I have found interesting is that depending on your life, your face changes with it. So, people who have had more laughter, more love, move positivity in their lives, tend to have much warmer expressions than people who’ve grown up in a stressful environment, or were abused as kids. Children in war-torn countries look very different than kids who grew up in a peaceful place, having been cared for by two parents.
Since the face has 43 muscles, our subconscious has learned to intuitively evaluate the look of the face and equate it to life experiences — on a level we don’t even realize. Even from personal experience, I can tell when someone is good or bad news for my life, just by monitoring his look, face and body energy. It’s fascinating, thank you for writing this.
