lifetime
/ˈlaɪftaɪm/
This word carries a weight of totality and finality. When applied to humans, it suggests the complete arc of existence from birth to death, often evoking a sense of legacy or the accumulation of a whole life's work. In commercial or technical contexts, the term shifts toward durability and reliability. It transforms from a biological reality into a performance metric, focusing on the point of failure or the end of utility for a product.
Countable when referring to the specific span of one individual or one product (a lifetime). Uncountable when discussing the general concept of the duration of life.
