Living Daylights

The "Living Daylights" refers to the limited time during which a person or object remains effective, functional, or relevant before conditions change or it becomes unsafe or obsolete. For example, medications have a "living daylights" period after which their potency diminishes, and equipment may have a functional lifespan. In a broader sense, it highlights the importance of timely action and awareness, emphasizing that opportunities, health, or resources are often temporary and require prompt attention to maintain their benefits or safety.
