Life expectancy is the expected (in the statistical sense) number of years of life remaining at a given age. It is denoted by ,[a] which means the average number of subsequent years of life for someone now aged , according to a particular mortality experience. Because life expectancy is an average, a particular person may well die many years before or many years after their "expected" survival. The term "maximum life span" has a quite different meaning. The "median life span" is also a different concept although fairly similar to life expectancy numerically in most developed countries.
The term that is known as life expectancy is most often used in the context of human populations, but is also used in plant or animal ecology; it is calculated by the analysis of life tables (also known as actuarial tables). The term life expectancy may also be used in the context of manufactured objects although the related term shelf life is used for consumer products and the terms "mean time to breakdown" (MTTB) and "mean time before failures" (MTBF) are used in engineering.
Actuarial science is the discipline that applies mathematical and statistical methods to assess risk in insurance, finance and other industries and professions. Actuaries are professionals who are qualified in this field through education and experience. In many countries, actuaries must demonstrate their competence by passing a series of rigorous professional examinations.
Actuarial science includes a number of interrelating subjects, including probability, mathematics, statistics, finance, economics, financial economics, and computer programming. Historically, actuarial science used deterministic models in the construction of tables and premiums. The science has gone through revolutionary changes during the last 30 years due to the proliferation of high speed computers and the union of stochastic actuarial models with modern financial theory (Frees 1990).

Vincent Jen Chin (simplified Chinese: 陈果仁; traditional Chinese: 陳果仁; pinyin: Chén Guǒrén; May 18, 1955 – June 23, 1982) was a Chinese American beaten to death in June 1982, in the enclave of Highland Park, Michigan, United States in Greater Detroit.
The perpetrators were Chrysler plant superintendent Ronald Ebens and his stepson, Michael Nitz. The murder generated public outrage over the lenient sentencing the two men originally received in a plea bargain, as the attack, which included blows to the head from a baseball bat, possessed many attributes consistent with hate crimes. Many of the layoffs in Detroit's auto industry, including Nitz's in 1979, had been due to the increasing market share of Japanese automakers, leading to allegations that Chinese American Vincent Chin received racially charged comments before his death.
