The disputed late-life mortality deceleration law states that death rates stop increasing exponentially at advanced ages and level off to the late-life mortality plateau. A consequence of this deceleration is that there would be no fixed upper limit to human longevity — no fixed number which separates possible and impossible values of lifespan.
Infographic comparing the number of humans in the past (red), present (green), and next 800,000 years (yellow), in a scenario where humanity's population stabilizes at 11 billion with a life expectancy of 88 years. [1] Longtermism is the ethical view that positively influencing the long-term future is a key moral priority of our time.
Life history theory has provided new perspectives in understanding many aspects of human reproductive behavior, such as the relationship between poverty and fertility. [43] A number of statistical predictions have been confirmed by social data [ citation needed ] and there is a large body of scientific literature from studies in experimental ...
"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.
Modern science indicates various ways in which genetics, diet, and lifestyle affect human longevity. It also allows us to determine the age of human remains with a fair degree of precision. The record for the maximum verified lifespan in the modern world is 122 + 1 ⁄ 2 years for women (Jeanne Calment) and 116 years for men (Jiroemon Kimura ...
The theory is based on the idea that ageing occurs over time due to the damage of the DNA. As an example, studies of mammalian brain and muscle have shown that DNA repair capability is relatively high during early development when cells are dividing mitotically, but declines substantially as cells enter the post-mitotic state.

Biological aging or the healthspan-lifespan gap (LHG) comes with a great cost burden to society, including potentially rising health care costs (also depending on types and costs of treatments). [151] [152] Scientists have noted that "[c]hronic diseases of aging are increasing and are inflicting untold costs on human quality of life". [152]
The longest documented human lifespan is 122 years 164 days, the case of Jeanne Calment, who according to records was born in 1875 and died in 1997, whereas the maximum lifespan of a wildtype mouse, commonly used as a model in research on aging, is about three years. [10]
