"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.
An alternative expression for the escape velocity v e particularly useful at the surface on the body is: = where r is the distance between the center of the body and the point at which escape velocity is being calculated and g is the gravitational acceleration at that distance (i.e., the surface gravity). [11]
Two of the most popular proponents of the anti-aging movement include Ray Kurzweil, who says humanity can defeat aging through the advance of technology, allowing us to reach the longevity escape velocity, [4] and Aubrey de Grey, who says that the human body is a very complicated machine and, thus, can be repaired indefinitely. [5]
This concept has been referred to as longevity escape velocity. Biomedical gerontology , also known as experimental gerontology and life extension, is a sub-discipline of biogerontology endeavoring to slow, prevent, and even reverse aging in both humans and animals.
David Gobel (born 1952 in Baltimore, Maryland) is an American philanthropist, entrepreneur, inventor, and futurist.He is co-founder and CEO of the Methuselah Foundation, CEO of the Methuselah Fund, and one of the first to publicly advance the idea of longevity escape velocity, even before this term was formulated.
The arrows with flat heads are a notation meaning "inhibits", used in the literature of gene expression and gene regulation. The term "negligible senescence" was first used in the early 1990s by professor Caleb Finch to describe organisms such as lobsters and hydras, which do not show symptoms of aging.
A 2009 review of longevity research noted: "Extrapolation from worms to mammals is risky at best, and it cannot be assumed that interventions will result in comparable life extension factors. Longevity gains from dietary restriction, or from mutations studied previously, yield smaller benefits to Drosophila than to nematodes, and smaller still ...
Fantastic Voyage: Live Long Enough to Live Forever (Rodale Books, ISBN 1-57954-954-3) is a book authored by Ray Kurzweil and Terry Grossman published in 2004. The basic premise of the book is that if middle aged people can live long enough, until approximately 120 years, they will be able to live forever—as humanity overcomes all diseases and old age itself.
