This book is so valuable--though I hope I never have to use the information here. It was published in 1997, but has aged well. It explains how to keep yourself safe and follow your instincts. Violence is not random--there are almost always warning signs. This book describes those warning signs in the context of strangers, coworkers, and people you know. Say "no" to people who intrude, and don't give qualifiers. It was hard to listen to some of the violent examples, but I understand why they were included. He also has some thoughts on how violence is portrayed in the media and on the news -- and in tv shows and movies. He also has some great thoughts on anxiety-type "fears" and actual fear--and how to distinguish the two. It tells you to trust your intuition-- those nagging feelings, persistent thoughts, humor, wonder anxiety,curiosity, hunches, gut feelings, doubt, hesitation, suspicion, apprehensions, and Fear.
