Longevity Escape Velocity
In the life extension movement, longevity escape velocity (LEV), actuarial escape velocity or biological escape velocity 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. For example, in a given year in which longevity escape velocity would be maintained, medical advances would increase people's remaining life expectancy more than the year that just went by. The term is meant as an analogy to the concept of escape velocity in physics, which is the minimum speed required for an object to indefinitely move away from a gravitational body despite the gravitational force pulling the object towards the body. Background For many years in the past, life expectancy at each age has increased slightly every year as treatment strategies and technologies have improved. At present, more than one year of research is required for each additional year of expected life. Longevity escape veloci ...

Live Long Enough To Live Forever
''Fantastic Voyage: Live Long Enough to Live Forever'' (Rodale Books, ) 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. This might also be considered a break-even scenario where developments made during a year increase life expectancy by more than one year. Biogerontologist Aubrey de Grey called this the "Longevity escape velocity" in a 2005 TED talk. The book focuses primarily on health topics such as heart disease, cancer, and type 2 diabetes. It promotes lifestyle changes such as a low glycemic index diet, calorie restriction, exercise, drinking green tea and alkalinized water, and other changes to daily living. They also promote aggressive supplementation to make up for nutrient deficiencies they believe are common in Western society. In contrast ...

Ageing
Ageing (or aging in American English) is the process of becoming older until death. The term refers mainly to humans, many other animals, and fungi; whereas for example, bacteria, perennial plants and some simple animals are potentially biologically immortal. In a broader sense, ageing can refer to single cells within an organism which have ceased dividing, or to the population of a species. In humans, ageing represents the accumulation of changes in a human being over time and can encompass physical, psychological, and social changes. Reaction time, for example, may slow with age, while memories and general knowledge typically increase. Of the roughly 150,000 people who die each day across the globe, about two-thirds die from age-related causes. Current ageing theories are assigned to the damage concept, whereby the accumulation of damage (such as DNA oxidation) may cause biological systems to fail, or to the programmed ageing concept, whereby the internal processes (e ...

Timeline Of Aging Research
This timeline lists notable events in the history of research into senescence or biological aging, including the research and development of Life extension#Strategies, life extension methods, Aging brain#Delaying the effects of aging, brain aging delay methods and rejuvenation. People have long been interested in making their lives longer and healthier. The most anсient Egyptian, Indian and Chinese books contain reasoning about aging. Ancient Egyptians used garlic in large quantities to extend their lifespan. Hippocrates (), in his ''Aphorisms'', and Aristotle (384 BCE, 384–322 BCE, 322 BCE), in ''On Youth, Old Age, Life and Death, and Respiration, On youth and old age'', expressed their opinions about reasons for old age and gave advice about lifestyle. Medieval Persian physician Ibn Sina ( – 1037), known in the West as Avicenna, summarized the achievements of earlier generations about this issue.

Transhumanism
Transhumanism is a philosophical and intellectual movement that advocates the human enhancement, enhancement of the human condition by developing and making widely available new and future technologies that can greatly enhance longevity, cognition, and well-being. Transhumanist thinkers study the potential benefits and dangers of emerging technologies that could overcome fundamental human limitations, as well as the technoethics, ethics of using such technologies. Some transhumanists speculate that human beings may eventually be able to transform themselves into beings of such vastly greater abilities as to merit the label of posthuman#Transhumanism, posthuman beings. Another topic of transhumanist research is how to protect humanity against existential risks from Existential risk from artificial general intelligence, artificial general intelligence, asteroid impact, gray goo, high-energy particle collision experiments, natural or synthetic pandemic, and nuclear warfare.

Technological Utopianism
Technological utopianism (often called techno-utopianism or technoutopianism) is any ideology based on the premise that advances in science and technology could and should bring about a utopia, or at least help to fulfill one or another utopian ideal. A techno-utopia is therefore an ideal society, in which laws, government, and social conditions are solely operating for the benefit and well-being of all its citizens, set in the near- or far-future, as advanced science and technology will allow these ideal living standards to exist; for example, post-scarcity, Trans-human, transformations in human nature, the avoidance or prevention of suffering and even the immortality, end of death. Technological utopianism is often connected with other discourses presenting technologies as agents of social and cultural change, such as technological determinism or Imaginary (sociology)#Media imaginary, media imaginaries. A tech-utopia does not disregard any problems that technology may cause, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rejuvenation
Rejuvenation is a medical discipline focused on the practical reversal of the aging process. Rejuvenation is distinct from life extension. Life extension strategies often study the causes of aging and try to oppose those causes to slow aging. Rejuvenation is the ''reversal'' of aging and thus requires a different strategy, namely repair of the damage that is associated with aging or replacement of damaged tissue with new tissue. Rejuvenation can be a means of life extension, but most life extension strategies do not involve rejuvenation. Historical and cultural background Various myths tell the stories about the quest for rejuvenation. It was believed that magic or intervention of a supernatural power can bring back youth and many mythical adventurers set out on a journey to do that, for themselves, their relatives or some authority that sent them anonymously. An ancient Chinese emperor sent out ships of young men and women to find a pearl that would rejuvenate him. This le ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pro-aging Trance
Pro-aging trance, also known as pro-aging edifice, is a term coined by British author and biomedical gerontologist Aubrey de Grey to describe the broadly positive and fatalistic attitude toward aging in society. Overview According to de Grey, the pro-aging trance explains why many people gloss over aging through irrational thought patterns. The concept says that the thought of one's own body slowly but ceaselessly deteriorating is so burdensome that it seems most sensible from a psychological point of view to try to put it out of one's mind. Since aging has been present throughout human history, this coping strategy would be deeply rooted in human thinking. It is striking that, in defending their point of view, those affected often commit fallacies which, from experience, would not be expected of them in a different context. The name, according to de Grey, comes from the similarity of persons affected to hypnotised people, whose subconscious minds in the trance state prefer t ...

Post-aging Society
The societal effects of negligible senescence considers a scenario where negligible senescence is achieved on a societal wide level in humans. There is much controversy about the realistic timeline of such a scenario. The predictions vary in time starting from 2037 till later than the 21st century. The effects of negligible senescence has a profound impact on economy, climate, demographics and impacts social structures. The baseline scenario ''ceteris paribus'' of negligible senescence is more population growth while a larger healthier labor force would spur economic growth. Definition and characteristics Senescence is defined as the gradual deterioration of functional characteristics. The word senescence can either refer to cell biology, cellular senescence or to senescence of a whole organism. Negligible senescence is therefore defined as the lack of senescence or a very small amount of senescence. Which implies that mortality rate, mortality and morbidity from most causes is eli ...

Life Extension
Life extension is the concept of extending the human lifespan, either modestly through improvements in medicine or dramatically by increasing the maximum lifespan beyond its generally-settled biological limit of around 125 years. Several researchers in the area, along with "life extensionists", " immortalists", or " longevists" (those who wish to achieve longer lives themselves), postulate that future breakthroughs in tissue rejuvenation, stem cells, regenerative medicine, molecular repair, gene therapy, pharmaceuticals, and organ replacement (such as with artificial organs or xenotransplantations) will eventually enable humans to have indefinite lifespans through complete rejuvenation to a healthy youthful condition (agerasia). The ethical ramifications, if life extension becomes a possibility, are debated by bioethicists. The sale of purported anti-aging products such as supplements and hormone replacement is a lucrative global industry. For example, the industry that ...

The Economist
''The Economist'' is a British newspaper published weekly in printed magazine format and daily on Electronic publishing, digital platforms. It publishes stories on topics that include economics, business, geopolitics, technology and culture. Mostly written and edited in London, it has other editorial offices in the United States and in major cities in continental Europe, Asia, and the Middle East. The newspaper has a prominent focus on data journalism and interpretive analysis over News media, original reporting, to both criticism and acclaim. Founded in 1843, ''The Economist'' was first circulated by Scottish economist James Wilson (businessman), James Wilson to muster support for abolishing the British Corn Laws (1815–1846), a system of import tariffs. Over time, the newspaper's coverage expanded further into political economy and eventually began running articles on current events, finance, commerce, and British politics. Throughout the mid-to-late 20th century, it greatl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Methuselarity
Methuselah (; ''Məṯūšélaḥ'', in pausa ''Məṯūšālaḥ'', "His death shall send" or "Man of the javelin" or "Death of sword"; ''Mathousalas'') was a biblical patriarch and a figure in Judaism, Christianity, and Islam. He is claimed to have lived the longest life, dying at 969 years of age. According to the Book of Genesis, Methuselah was the son of Enoch, the father of Lamech, and the grandfather of Noah. Elsewhere in the Bible, Methuselah is mentioned in genealogies in 1 Chronicles and the Gospel of Luke. His life is described in further detail in other texts such as the Book of Enoch, Slavonic Enoch, and the Book of Moses. Bible commentators have offered various explanations as to why the Book of Genesis describes him as having died at such an advanced age; some believe that Methuselah's age is the result of a mistranslation, while others believe that his age is used to give the impression that part of Genesis takes place in a very distant past.
