Fear is in the forefront of our lives. Imagine what would happen if a person lost his sense of fear: he could jump without hesitation from the 20th floor. Sometimes it helps us to survive, but more often it kills us. So what is fear? Is it good or bad? And, finally, is it possible to get rid of it and if so, what will be the consequences? Genetically, we have an instinct for self-preservation. And with this inseparably linked are such sensations as pain and fear. And if the pain is good, because it makes us realize that we are still alive, then what can fear do to us? In fact, it is different. We are afraid of darkness, heights, insects, walking alone in the night city. In childhood, each of us was afraid of monsters under the bed or vaccinations.
