Longevity may refer to especially long-lived members of a population, whereas life expectancy is defined statistically as the average number of years remaining at a given age. For example, a population's life expectancy at birth is the same as the average age at death for all people born in the same year (in the case of cohorts).
A cognate Latin word aevum (cf. αἰϝών) for "age" is present in words such as eternal, longevity and mediaeval. [ 3 ] Although the term aeon may be used in reference to a period of a billion years (especially in geology , cosmology and astronomy ), its more common usage is for any long, indefinite period.

In a new study, researchers were able to influence someone's estimate of their lifespan -- by more than nine years -- simply by asking them if they expected to "live to" versus "die by" a certain age.
Life extension is the concept of extending the human lifespan, either modestly through improvements in medicine or dramatically by increasing the maximum lifespan beyond its generally-settled biological limit of around 125 years. [1]
By another definition, however, maximum life span corresponds to the age at which the oldest known member of a species or experimental group has died. Calculation of the maximum life span in the latter sense depends upon the initial sample size. [1] Maximum life span contrasts with mean life span (average life span, life expectancy), and longevity.
