The extraction from literature vividly illustrates the perilous situations where the sea's whims can dictate a person's survival and how life-saving devices like life-preservers and lifejackets can make a significant difference in emergency situations like being tossed into the water or dealing with currents.
Wearing a lifejacket increases one's chances of survival and being rescued, by ensuring that the person remains on the water's surface and is visible to rescuers. Despite the exhaustion depicted in the scenario, the presence of a flotation device provides a critical advantage for staying alive in the ocean's unpredictable conditions.
Falls overboard and capsizing demonstrate the importance of wearing a lifejacket in water-related emergencies.
