Life expectancy development in some big countries of the world since 1960 Life expectancy at birth, measured by region, between 1950 and 2050 Life expectancy by world region, from 1770 to 2018 Human life expectancy is a statistical measure of the estimate of the average remaining years of life at a given age.
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).
An example would be to allow workers to take some risks and not punish them if the risks leads to unsuccessful outcomes. "In short, work engagement can be thought of as an interaction of individuals and work. Engagement can occur when both facilitate each other, and engagement will not occur when either (or both) thwarts each other."
The design life of a component or product is the period of time during which the item is expected by its designers to work within its specified parameters; in other words, the life expectancy of the item. Engineers follow a theory to calculate the life expectancy from expected conditions, uses and physical properties. [1]
Self-estrangement is when a person feels alienated from others and society as a whole. A person may feel alienated by his work by not feeling like he has meaning to his work, therefore losing their sense of self at the work place. Self-estrangement contributes to burnout at work and a lot of psychological stress. [3]
He also originated the concepts of lifestyle (1929—he defined "lifestyle" as an individual's characteristic approach to life, in facing problems) and of self-image, [31] as a concept that influenced management under the heading of work-life balance, also known as the equilibrium between a person's career and personal life.

A microlife is a unit of risk representing half an hour change of life expectancy. [1]Discussed by David Spiegelhalter and Alejandro Leiva, and also used by Lin et al. [2] for decision analysis, microlives are intended as a simple way of communicating the impact of a lifestyle or environmental risk factor, based on the associated daily proportional effect on expected length of life.
"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.
