School life expectancy is a measure of how many years of education a child of school-entering age would receive during their lifetime if the school enrollment rates stay the same as of today. It is computed by UNESCO Institute for Statistics and is used by statisticians and organisations to compare and assess the development of nations.
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). Longevity studies may involve putative methods to extend life. Longevity has been a topic not only for the scientific community but also for writers of travel, science fiction, and utopian ...
"The first 1000-year-old is probably only ~10 years younger than the first 150-year-old."–Aubrey de Grey, 2005 [1]. In the life extension movement, longevity escape velocity (LEV), actuarial escape velocity [2] or biological escape velocity [3] is a hypothetical situation in which one's remaining life expectancy (not life expectancy at birth) is extended longer than the time that is passing.
Human life expectancy is a statistical measure of the estimate of the average remaining years of life at a given age. The most commonly used measure is life expectancy at birth (LEB, or in demographic notation e 0, where e x denotes the average life remaining at age x). This can be defined in two ways.
That was the life expectancy at birth, which was skewed by high infant and adolescent mortality. The life expectancy among adults was much higher; [296] a 21-year-old man in medieval England, for example, could expect to live to the age of 64. [297] [296] However, in various places and eras, life expectancy was noticeably lower. For example ...

Biology appears in fiction, especially but not only in science fiction, both in the shape of real aspects of the science, used as themes or plot devices, and in the form of fictional elements, whether fictional extensions or applications of ...
