vigilance

What does "vigilance" mean?
Vigilance is the state of keeping careful watch for possible danger or difficulties. Imagine a sentry standing on a wall at night, eyes scanning the horizon for any hint of movement; that sustained, alert state of mind is the essence of vigilance. It is a formal term often used in contexts of security, medical monitoring, or high-stakes responsibility. While "alertness" suggests a temporary state, "vigilance" implies a persistent, intentional commitment to being watchful over a long period.
