  2. Longevity escape velocity - Wikipedia

    en.wikipedia.org/wiki/Longevity_escape_velocity

    "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.

  3. Gompertz–Makeham law of mortality - Wikipedia

    en.wikipedia.org/wiki/Gompertz–Makeham_law_of...

    The Gompertz–Makeham law of mortality describes the age dynamics of human mortality rather accurately in the age window from about 30 to 80 years of age. At more advanced ages, some studies have found that death rates increase more slowly – a phenomenon known as the late-life mortality deceleration [2] – but more recent studies disagree. [4]

    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.

    Life expectancy in the U.S. is projected to increase from 78.3 years in 2022 to 79.9 years in 2035 and to 80.4 years in 2050 for all sexes combined, researchers said.

  6. Psychrometrics - Wikipedia

    en.wikipedia.org/wiki/Psychrometrics

    A psychrometric chart is a graph of the thermodynamic parameters of moist air at a constant pressure, often equated to an elevation relative to sea level. The ASHRAE-style psychrometric chart, shown here, was pioneered by Willis Carrier in 1904. [10] It depicts these parameters and is thus a graphical equation of state. The parameters are:

    The tasers — and nearly obsolete dashcams — were grouped into the total body cam estimate of $1.34 million per year. But those need replacing regardless.

  8. Microlife - Wikipedia

    en.wikipedia.org/wiki/Microlife

    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.

  9. List of countries by life expectancy - Wikipedia

    This is especially true for Healthy life expectancy, the definition of which criteria may change over time, even within a country. For example, Canada is a country with a fairly high overall life expectancy at 81.63 years; however, this number decreases to 75.5 years for Indigenous people in the country. [4]
