Do you have to worry about your co-worker, nanny, neighbor, or date? If you're concerned about a new relationship, or even an old one, you will no longer need to rely on instincts, hunches, or horoscopes. Even when interaction is limited to mere observation or a brief exchange, whether you're at a bar, restaurant, park, or even in an elevator, you can discover how to assess the general emotional stability of a person in just minutes. The legendary leader in human behavior, Dr. David J. Lieberman, shows you how to protect yourself and your loved ones --emotionally, financially, and physically--from unstable individuals who will inevitably pass through your life. He has personally trained the military, FBI, and mental-health professionals around the world on how to eliminate the guesswork and learn in person, online, or even over the phone virtually foolproof tactics to find out if a person is normal, neurotic, or something far more dangerous.
