Stuff you need to know:
- Body language, which consists of hand and arm gestures, body position and movements, and facial expressions and eye movements, can reveal what we're thinking to other people -- usually without our even realizing it.
- Evolutionary researchers believe that the ability to interpret subtle physical signs and to make judgments about a person based on those signs is something the human species developed long before verbal human language.
- Body language, like spoken language, tends to vary from culture to culture. Gestures can have very different meanings in different countries.
- By studying nonverbal communication and training yourself, it's possible to shape body language deliberately to convey a chosen message or impression.
