The term "longevity" primarily refers to the duration of time that an individual or thing is able to exist or endure, particularly in the context of life span. While "lifetime" conveys the idea of the entire span of an individual's life, from birth to death, it carries the connotation of measuring the length of time one lives, which aligns closely with the concept of longevity. Longevity often encompasses a prolonged or extended life, highlighting not just the time lived, but also the quality and health of that life.

In contrast, "duration" refers more broadly to the length of time something lasts but doesn't specifically imply the idea of a life span, making it a less precise match. "Timeliness" relates to being appropriate or opportune in timing, which diverges from the concept of longevity altogether. Finally, "fleeting" suggests something transient or quickly passing, which is in direct opposition to the idea of longevity, as it implies a short existence or life span. Therefore, the understanding of longevity is best encapsulated by the term "lifetime."
