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.
The rhizosphere is the thin area of soil immediately surrounding the root system. It is a densely populated area in which the roots compete with invading root systems of neighboring plant species for space, water, and mineral nutrients as well as form positive and negative relationships with soil-borne microorganisms such as bacteria, fungi and insects.
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]
How long can a human live? Jeanne Calment, the world’s oldest person, offers a ceiling of 122 years and 164 days. But researchers have pondered that the limit could be around 150 years, and ...
The researchers found that since 1990, the average lifespan has only risen 6.5 years in the countries in the study, which causes uncertainty in expectations that human life expectancy would exceed ...

It was co-founded in 2003 by Aubrey de Grey and David Gobel, and is based in Springfield, Virginia, United States.
The rise in human life expectancy may be slowing down after nearly doubling over the last century, new research suggests. Over the 19th and 20th centuries, there have been dramatic increases in ...

The concept of adulthood has legal and socio-cultural definitions. The legal definition [4] of an adult is a person who is fully grown or developed.
