Longevity escape velocity

Longevity escape velocity is a term used in the life extension movement. It is a hypothetical situation in which life expectancy is faster than time is expended. For example, in a given year in which longevity escape would be maintained,

Not immortality

The terms ” immortality ” and ” eternal youth ” are often used as synonyms for “indefinite lifespan”, but they carry connotations from their other contexts which has not been possible. That is, immortal means “incapable of dying”. Eternal Implies guaranteed existence for eternity , and in this context est implausible Because of entropy . Even if cures were found for all the degenerative diseases, and effective treatments were developed for all the processes of aging, they could easily be repaired, people would still be killed in accidents , slain in wars , to die, etc.

The term indefinite lifespan represents a more achievable state of affairs, because it simply implies freedom from death by aging or infirmity.

The use of the term is also sometimes favored for reasons of linguistic aesthetics, in the same way that the term birth control is preferred to ” birth prevention ” or ” birth elimination ” which both imply, as does “immortality”, that the choice is one-time only and has permanent consequences. The point of ‘indefinite lifespan’, like the point of ‘birth control’, is to gain the opportunity to lead one’s life in a more conscious and deliberate manner.

Probability

This question is twofold. “Will a cure (or program of effective treatments) for aging ever be developed?” “Can the effective treatment of aging become more of a reality?” The answer to the first question is conditional on medical advancement: if medical science continues to advance in the fields of biogerontology and bioengineering , then some people hope the answer is “yes, it will happen eventually, except for some event or series of events were to prevent the further advance of biological science “( see Risks to civilization, Humans and Planet Earth and the Doomsday Clock). Many scientists researching this area at the moment do not agree. They see a problem in the field of thermodynamic considerations. ^{[ quote needed ]}

While science is constantly evolving and technology is becoming more and more sophisticated, the human body is evolving very slowly, and the aging process has become more damaging ( which, in short, is why we live times as long as average in the twenty-first century as we did ten thousand years before ). ^[1]

The answer to the second issue depends are two factors: the first being white how fast medical science advances, and the second being white how well Each person takes care of themself (Such As Utilizing the best available life extension technology or not, and Generally eating and behaving in a healthful and non-degrading way), wherein the treatment becomes available. This strategy is captured in the subtitle “Live Long Enough to Live Forever” by Fantastic Voyage , by Ray Kurzweil and Terry Grossman . ^{[ quote needed ]}

The second factor to the second question in the first case – no amount of healthy living will be important if it is not . However, if biomedical gerontology continues to improve, if somatic genetic engineering becomes safe and effective, it may be conceivable for some of those now alive to attain indefinite lifespans. ^{[ quote needed ]}

According to biogerontologist Marios Kyriazis , indefinite lifespans will become possible (even inevitable) because of inherent properties of natural laws governing human evolution. ^[2] Kyriazis believes that ^[3] as human is enhanced by technology, human evolution will become redundant, and humans will continue to evolve through an indefinitely-long process of self-development. This process will necessitate the elimination of death due to aging. ^[4]

Proposed techniques

Strategies for Engineered Negligible Senescence is a proposed research program for repairing all types of age-related damage.

Calorie restriction has been presented as a piece of the puzzle of reaching escape velocity. ^{[5] [6] [7]} Other proposed techniques include genetic engineering , telomere extension, organ regeneration, nanotechnology , and even mind uploading . ^[8]

On the theory que la primary causes of aging is DNA damage [see DNA damage theory of aging and DNA damage (naturally Occurring) ], there are, in principle, two ways of Reducing DNA damage in cells, and THUS Allowing indefinite extension of lifespan . These are:

1. Preventing the occurrence of DNA damage, and
2. Repairing the DNA damage after it has occurred.

There is a large body of literature on antioxidant phytochemicals that reduce the occurrence of oxidative DNA damage. However, when these procedures were carried out using these antioxidants, the results were generally disappointing. ^[9] [10]

There is evidence that certain dietary components stimulate DNA damage, and protect against cancer as an endpoint. One of these is a chlorogenic acid , a major component of, and absorbable from, coffee. ^[11] Coffee is protective against colorectal cancer, ^[12] and chlorogenic acid and its metabolites increase the protein expression levels of DNA repair enzymes: Pms2 and PARP. ^[13] Another compound that protects against the early stages of cancer is naringenin , a citrus flavonoid . ^[14] Naringenin was shown to increase mRNA expression levels of DNA repair enzymes, DNA pol betaand OGG1 . ^[15]
