Maximum life span is a measure of the maximum amount of time one or more members of a population has been observed to survive between birth and death. The term can also denote an estimate of the maximum amount of time that a member of a given species could survive between life and death, provided optimal circumstances.
Most living species have at least one upper limit on the number of times cells can divide. For humans, this is called the Hayflick limit, although number of cell divisions does not strictly control lifespan (non-dividing cells and dividing cells lived over 120 years in the oldest known human).

“Look at your [English] ladies of quality—are they not forever parting with their husbands—forfeiting their reputations—and is their life aught but dissipation? In common genteel life, indeed, you may now and then meet with very fine girls—who have politeness, sense and conversation—but these are few—and then look at your trademen’s daughters—what are they?—poor creatures indeed! all pertness, imitation and folly.”
—Frances Burney (1752–1840)
“What a large volume of adventures may be grasped within this little span of life by him who interests his heart in every thing, and who, having eyes to see, what time and chance are perpetually holding out to him as he journeyeth on his way, misses nothing he can fairly lay his hands on.”
—Laurence Sterne (1713–1768)
