Gestures: A Warning System

Gestures act as an early warning system for intent, emotion, and mood. Our body language precedes the desire of our conscious minds. Our bodies know what we want before our conscious minds do.

So it's useful to watch others' body language to know what they're thinking, desiring, and feeling. In turn, we have to learn to listen to our unconscious mind. It's telling you that you're hungry, angry, bored, happy, and content.
