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).
