Imagine that you've had a weathered old treasure map lying around your house for years. People told you that it's a real treasure map, and yet for some reason, you never got around to following it. Finally, one day, out of curiosity, you say, "What the hell -- let's see where this takes us." You follow the map, and -- you find treasure! Who knew.That's how I feel about "Love Signals" by Dr David Givens. I had known about its existence for years, but only now finally got to reading the whole book. What a treat! It is full of fascinating, little-known yet totally essential facts about how human beings operate in the world. I thought I had read every book under the sun about love and courtship, and yet this book contained reams of entirely brand-new data for me. I must have highlighted a good 40% of the text. Some delightful things I had never heard of before:-- Lip compression and showing the tip of the tongue are unconscious aversive signals. If you do them, people will stay away, and you won't even know why.-- Trigeminal taste, related to what people would call "heat" or "spiciness", is unexpectedly arousing-- The importance of signaling vulnerability for a successful approach (eg through pigeon toes or an exposed neck), especially if you're a guy.I particularly like that fact that Dr Givens has done a lot of the primary research himself and presents the data to you with the rigor and care of a scientist. No wildcat anecdotal claims in this book: everything is amply supported by peer-reviewed observation. The information in this book is so esssential and yet so little-known by the general public that it should be called "The Book of Secrets." And yet, here it is, hiding in plain sight. If you're interested in improving your love life or understanding humans a little bit better, this is essential reading.-- Ali Binazir, M.D., M.Phil., author of The Tao of Dating: The Smart Woman's Guide to Being Absolutely Irresistible, the highest-rated dating book on Amazon for 157 weeks
