Fear is an inherent emotion that has been part of human experience since the beginning of time. It is a fundamental feeling that drives people’s actions and decisions, often influencing their responses to various situations. In Max Brooks' "World War Z: An Oral History of the Zombie War," this primal emotion takes center stage, revealing how fear can shape societies and beliefs during crises. The narrative explores the depth of fear experienced during catastrophic events, highlighting its impact on both individuals and communities.

Moreover, fear has a unique ability to engage and captivate audiences, making it a powerful tool, especially in storytelling and sales. The idea that "fear sells" emphasizes how marketers and creators use fear to evoke reactions and draw people in. Brooks deftly illustrates this concept, showing that in times of upheaval, fear is not just a response but a means of fueling survival instincts, demonstrating its role in shaping human behavior in extreme circumstances.
