Book excerpt: Imagine yourself sitting in front of your fireplace inside your cave 20 thousand years ago and suddenly you hear a loud thrusting and eerie noise. You take a look outside and see a bright light that disappears in a blink of an eye followed by its thrusting noise. Yes, that's the sound of thunder! But, you take a look at your comrades, and they all seem frightened, why? 20 thousand years ago, there was a myth that thunder was a result anger cumulated by the Gods towards humans. Fortunately enough, that wasn't the case when we started investigating and observing rationally. Human myths and "truths" have been around since all the way back then. This book will take a look at modern myths and investigate them to see what's their worth. Myths such as the left/right brain personality, 10% usage of the brain "power", and other interesting "truths". Are these "truth" just a myth or do they hold their ground? Well, my dear, by the end you will find out".
