The quote from Robert Kurson's "Shadow Divers" highlights the tragic reality of divers who lost their lives in shipwrecks despite having enough air to return to safety. It suggests that these individuals faced a mental battle that rendered them incapable of finding a way to survive, rather than a physical inability to breathe. This insight emphasizes the psychological challenges that can accompany extreme situations.

Kurson's narrative underscores the notion that life-or-death decisions in perilous environments are not solely based on the physical aspects of survival. Instead, emotional and mental clarity play crucial roles in whether individuals can navigate their circumstances effectively. The quote serves as a poignant reminder of the complexities of human resilience and the profound impact of fear and confusion in life-threatening situations.
