THE DEFINITIVE BOOK OF BODY LANGUAGE

You can look this up on Amazon, but it's basically from a former sales guy who learned through experience and science the different meanings behind body language. I read it to get some insight into poker tells, but it really wasn't meant for that.

Anyway, it lists some "power words" that are the most persuasive words in spoken language. They are: discovery, guarantee, love, proven, results, save, easy, health, money, new, safety and you.

Here are the Seven Secrets of Attractive Body Language

Face: Have an animated face and make smiling a part of your regular repertoire. Make sure you flash your teeth.

Gestures: Be expressive but don't overdo it. Keep your fingers closed when you gesture, your hands below chin level, and avoid arm or feet crossing.

Head Movement: Use triple nods when talking and head tilt when listening. Keep your chin up.

Eye Contact: Give the amount of eye contact that makes everyone feel comfortable. Unless looking at others is a cultural no-no, lookers gain more credibility than nonlookers.

Posture: Lean forward when listening, stand straight when speaking.

Territory: Stand as close as you feel comfortable. If the other person moves back, don't step forward again.

Mirror: Subtly mirror the body language of others.
