Revision as of 16:26, 18 February 2013

Comparison of male and female life expectancy at birth for countries and territories as defined in the 2011 CIA Factbook, with selected bubbles labelled. The green dotted line corresponds to equal female and male life expectancy. The apparent 3D volumes of the bubbles are linearly proportional to their population.

The word "longevity" is sometimes used as a synonym for "life expectancy" in demography - especially when it concerns someone or something lasting longer than expected (an ancient tree, for example) - however, the two words have slightly different definitions. In a similar dichotomy to "precision" and "accuracy", "longevity" refers to the average number of years that a single person lives, whereas "life expectancy" refers to the number of years that the average population lives. This is illustrated by the fact that a drastic increase in life expectancy (due to a larger portion of the population beginning to live longer) may be accompanied by a small increase in the overall longevity of the population.

Reflections on longevity have usually gone beyond acknowledging the brevity of human life and have included thinking about methods to extend life. Longevity has been a topic not only for the scientific community but also for writers of travel, science fiction, and utopian novels.

There are many difficulties in authenticating the longest human life span ever by modern verification standards, owing to inaccurate or incomplete birth statistics. Fiction, legend, and folklore have proposed or claimed life spans in the past or future vastly longer than those verified by modern standards, and longevity narratives and unverified longevity claims frequently speak of their existence in the present.

A life annuity is a form of longevity insurance.

History

A remarkable statement mentioned by Diogenes Laertius (c. 250 AD) is the earliest (or at least one of the earliest) references about plausible centenarian longevity given by a scientist, the astronomer Hipparchus of Nicea (c. 185 – c. 120 BC), who, according to the doxographer, was assured that the philosopher Democritus of Abdera (c. 470/460 – c. 370/360 BC) lived 109 years. All other accounts given by the ancients about the age of Democritus appear, without giving any specific age, to agree that the philosopher lived over 100 years. This possibility is likely, given that many ancient Greek philosophers are thought to have lived over the age of 90 (e.g., Xenophanes of Colophon, c. 570/565 – c. 475/470 BC, Pyrrho of Ellis, c. 360 – c. 270 BC, Eratosthenes of Cirene, c. 285 – c. 190 BC, etc.). The case of Democritus is different from the case of, for example, Epimenides of Crete (7th, 6th centuries BC), who is said to have lived 154, 157 or 290 years, as has been said about countless elders even during the last centuries as well as in the present time. These cases are not verifiable by modern means.

Present life expectancy

Main article: List of countries by life expectancy

Various factors contribute to an individual's longevity. Significant factors in life expectancy include gender, genetics, access to health care, hygiene, diet and nutrition, exercise, lifestyle, and crime rates. Below is a list of life expectancies in different types of countries:

Population longevities are increasing as life expectancies around the world grow:

  • Spain: 79.08 years in 2002, 81.07 years in 2010
  • Australia: 80 years in 2002, 81.72 years in 2010
  • Italy: 79.25 years in 2002, 80.33 years in 2010
  • France: 79.05 years in 2002, 81.09 years in 2010
  • Germany: 77.78 years in 2002, 79.41 years in 2010
  • UK: 80 years in 2002, 81.73 years in 2010
  • USA: 77.4 years in 2002, 78.24 years in 2010
  • Monaco: 79.12 years in 2002, 89.73 years in 2011

Long-lived individuals

The Gerontology Research Group validates current longevity records by modern standards, and maintains a list of supercentenarians; many other unvalidated longevity claims exist. Record-holding individuals include:

  • Geert Adriaans Boomgaard (1788–1899, 110 years, 135 days): first person to reach the age of 110 (on September 21, 1898) and whose age could be validated.
  • Jeanne Calment (1875–1997, 122 years, 164 days): the oldest person in history whose age has been verified by modern documentation. This defines the modern human life span, which is set by the oldest documented individual who ever lived.
  • Sarah Knauss (1880–1999, 119 years, 97 days): the second oldest documented person in modern times and the oldest American.
  • Jiroemon Kimura (born 1897): celebrated his 115th birthday in April 2012, currently the oldest living person and the oldest man in history whose age has been verified by modern documentation.
  • Misao Okawa (born 1898): the oldest living woman in the world.

Longevity and lifestyle

Evidence-based studies indicate that longevity is based on two major factors, genetics and lifestyle choices. Twin studies have estimated that approximately 20-30% of an individual’s lifespan is related to genetics, the rest is due to individual behaviors and environmental factors which can be modified. Recent studies find that even modest amounts of leisure time physical exercise can extend life expectancy by as much as 4.5 years

In preindustrial times, deaths at young and middle age were common, and lifespans over 70 years were comparatively rare. This is not due to genetics, but because of environmental factors such as disease, accidents, and malnutrition, especially since the former were not generally treatable with pre-20th century medicine. Deaths from childbirth were common in women, and many children did not live past infancy. In addition, most people who did attain old age were likely to die quickly from the above-mentioned untreatable health problems. Despite this, we do find a large number of examples of pre-20th century individuals attaining lifespans of 75 years or greater, including Benjamin Franklin, Thomas Jefferson, John Adams, Cato the Elder, Thomas Hobbes, Eric of Pomerania, Christopher Polhem, and Michaelangelo. This was also true for poorer people like peasants or laborers. Genealogists will almost certainly find ancestors living to their 70s, 80s and even 90s several hundred years ago.

For example, an 1871 census in the UK (the first of its kind) found the average male life expectancy as being 44, but if infant mortality is subtracted, males who lived to adulthood averaged 75 years. The present male life expectancy in the UK is 77 years for males and 81 for females (the United States averages 74 for males and 80 for females).

Studies have shown that African-American males have the shortest lifespans of any group of people in the US, averaging only 69 years (Asian American females average the longest). This reflects overall poorer health and greater prevalence of heart disease, obesity, diabetes, and cancer among African-American men.

Women normally outlive men, and this was as true in pre-industrial times as today. Theories for this include smaller bodies (and thus less stress on the heart), a stronger immune system (since testosterone acts as an immunosuppressant), and less tendency to engage in physically dangerous activities. It is also theorized that women have an evolutionary reason to live longer so as to help care for grandchildren and great-grandchildren.

Study of the regions of the world known as blue zones, where people commonly live active lives past 100 years of age, have speculated that longevity is related to a healthy social and family life, not smoking, eating a plant-based diet, frequent consumption of legumes and nuts, and engaging in regular physical activity. In another well-designed cohort study, the combination of a plant based diet, frequent consumption of nuts, regular physical activity, normal BMI, and not smoking accounted for differences up to 10 years in life expectancy. The Alameda County Study hypothesized three additional lifestyle characteristics that promote longevity: limiting alcohol consumption, sleeping 7 to 8 hours per night, and not snacking (eating between meals).

Alcohol use

A meta-analysis found with data from 477,200 individuals determined the dose-response relationships by sex and end point using lifetime abstainers as the reference group. The search revealed 20 cohort studies that met our inclusion criteria. A U-shaped relationship was found for both sexes. Compared with lifetime abstainers, the relative risk (RR) for type 2 diabetes among men was most protective when consuming 22 g/day alcohol (RR 0.87 ) and became deleterious at just over 60 g/day alcohol (1.01 ). Among women, consumption of 24 g/day alcohol was most protective (0.60 ) and became deleterious at about 50 g/day alcohol (1.02 ).

Interestingly, ethanol has been found to double the lifespans of worms feed 0.005% ethanol but does not markedly increase at higher concentrations. Supplementing starved cultures with n-propanol and n-butanol also extended lifespan.; 1-Propanol (n-propanol) is thought to be similar to ethanol in its effects on human body, but 2-4 times more potent. However, this seems to be statistically significant for humans when compared to the previous study discusses; Human macronutrients in food consist mainly of water and the Dietary Reference Intake (DRI) for water is 3.7 litres (3700 mL x 0.005% EtOH = 18.5 mL EtOH) for 19-70 year old males, and 2.7 litres (2700 mL x 0.005% EtOH = 13.5 mL) for 19-70 year old women.

Because former drinkers may be inspired to abstain due to health concerns, they may actually be at increased risk of developing diabetes, known as the sick-quitter effect. Moreover, the balance of risk of alcohol consumption on other diseases and health outcomes, even at moderate levels of consumption, may outweigh the positive benefits with regard to diabetes.

Additionally, the way in which alcohol is consumed (i.e., with meals or bingeing on weekends) affects various health outcomes. Thus, it may be the case that the risk of diabetes associated with heavy alcohol consumption is due to consumption mainly on the weekend as opposed to the same amount spread over a week. In the United Kingdom "advice on weekly consumption is avoided".

In a 2010 long-term study of an older population, the beneficial effects of moderate drinking were confirmed, but abstainers and heavy drinkers showed an increase of about 50% in mortality (even after controlling for confounding factors).

Longevity traditions

Main articles: Longevity traditions and Longevity claims

Longevity traditions are traditions about long-lived people (generally supercentenarians), and practices that have been believed to confer longevity. A comparison and contrast of "longevity in antiquity" (such as the Sumerian King List, the genealogies of Genesis, and the Persian Shahnameh) with "longevity in historical times" (common-era cases through twentieth-century news reports) is elaborated in detail in Lucian Boia's 2004 book Forever Young: A Cultural History of Longevity from Antiquity to the Present and other sources.

The Fountain of Youth reputedly restores the youth of anyone who drinks of its waters. The New Testament, following older Jewish tradition, attributes healing to the Pool of Bethesda when the waters are "stirred" by an angel. After the death of Juan Ponce de León, Gonzalo Fernández de Oviedo y Valdés wrote in Historia General y Natural de las Indias (1535) that Ponce de León was looking for the waters of Bimini to cure his aging. Traditions that have been believed to confer greater human longevity also include alchemy, such as that attributed to Nicolas Flamel. In the modern era, the Okinawa diet has some reputation of linkage to exceptionally high ages.

More recent longevity claims are subcategorized by many editions of Guinness World Records into four groups: "In late life, very old people often tend to advance their ages at the rate of about 17 years per decade .... Several celebrated super-centenarians (over 110 years) are believed to have been double lives (father and son, relations with the same names or successive bearers of a title) .... A number of instances have been commercially sponsored, while a fourth category of recent claims are those made for political ends ...." The estimate of 17 years per decade was corroborated by the 1901 and 1911 British censuses. Mazess and Forman also discovered in 1978 that inhabitants of Vilcabamba, Ecuador, claimed excessive longevity by using their fathers' and grandfathers' baptismal entries. Time magazine considered that, by the Soviet Union, longevity had been elevated to a state-supported "Methuselah cult". Robert Ripley regularly reported supercentenarian claims in Ripley's Believe It or Not!, usually citing his own reputation as a fact-checker to claim reliability.

Future

The U.S. Census Bureau view on the future of longevity is that life expectancy in the United States will be in the mid-80s by 2050 (up from 77.85 in 2006) and will top out eventually in the low 90s, barring major scientific advances that can change the rate of human aging itself, as opposed to merely treating the effects of aging as is done today. The Census Bureau also predicted that the United States would have 5.3 million people aged over 100 in 2100. The United Nations has also made projections far out into the future, up to 2300, at which point it projects that life expectancies in most developed countries will be between 100 and 106 years and still rising, though more and more slowly than before. These projections also suggest that life expectancies in poor countries will still be less than those in rich countries in 2300, in some cases by as much as 20 years. The UN itself mentioned that gaps in life expectancy so far in the future may well not exist, especially since the exchange of technology between rich and poor countries and the industrialization and development of poor countries may cause their life expectancies to converge fully with those of rich countries long before that point, similarly to the way life expectancies between rich and poor countries have already been converging over the last 60 years as better medicine, technology, and living conditions became accessible to many people in poor countries. The UN has warned that these projections are uncertain, and cautions that any change or advancement in medical technology could invalidate such projections.

Recent increases in the rates of lifestyle diseases, such as obesity, diabetes, hypertension, and heart disease, may drastically slow or reverse this trend toward increasing life expectancy in the developed world.

Scientist Olshansky examined how much mortality from various causes would have to drop in order to boost life expectancy and concluded that most of the past increases in life expectancy occurred because of improved survival rates for young people. He states that it seems unlikely that life expectancy at birth will ever exceed 85 years.

However, since 1840, record life expectancy has risen linearly for men and women, albeit more slowly for men. For women the increase has been almost three months per year. In light of steady increase, without any sign of limitation, the suggestion that life expectancy will top out must be treated with caution. Scientists Oeppen and Vaupel observe that experts who assert that "life expectancy is approaching a ceiling ... have repeatedly been proven wrong." It is thought that life expectancy for women has increased more dramatically owing to the considerable advances in medicine related to childbirth.

Mice have been genetically engineered to live twice as long as ordinary mice. Drugs such as deprenyl are a part of the prescribing pharmacopia of veterinarians specifically to increase mammal lifespan. A large plurality of research chemicals have been described at the scientific literature that increase the lifespan of a number of species.

Some argue that molecular nanotechnology will greatly extend human life spans. If the rate of increase of life span can be raised with these technologies to a level of twelve months increase per year, this is defined as effective biological immortality and is the goal of radical life extension.

Non-human biological longevity

Main article: List of long-living organisms

Currently living:

Non-living:

  • Possibly 250 million year-old bacteria, bacillus permians, were revived from stasis after being found in sodium chloride crystals in a cavern in New Mexico. Russell Vreeland, and colleagues from West Chester University in Pennsylvania, reported on October 18, 2000 that they had revived the halobacteria after bathing them with a nutrient solution. Having supposedly survived for 250 million years, they would be the oldest living organisms ever recorded. However, their findings have not been universally accepted.
  • A bristlecone pine nicknamed "Prometheus", felled in the Great Basin National Park in Nevada in 1964, found to be about 4,900 years old, is the longest-lived single organism known.
  • The quahog clam (Arctica islandica) is exceptionally long-lived, with a maximum recorded age of 507 years, the longest of any animal. Other clams of the species have been recorded as living up to 374 years.
  • Lamellibrachia luymesi, a deep-sea cold-seep tubeworm, is estimated to reach ages of over 250 years based on a model of its growth rates.
  • Hanako (Koi Fish) was the longest-lived vertebrate ever recorded at 226 years.
  • A Bowhead Whale killed in a hunt was found to be approximately 211 years old (possibly up to 245 years old), the longest lived mammal known.
  • Tu'i Malila, a radiated tortoise presented to the Tongan royal family by Captain Cook, lived for over 185 years. It is the oldest documented reptile. Adwaitya, an Aldabra Giant Tortoise, may have lived for up to 250 years.

Biological immortality

Main article: Biological immortality

Certain exotic organisms do not seem to be subject to aging and can live indefinitely. Examples include Tardigrades and Hydras. That is not to say that these organisms cannot die, merely that they only die as a result of disease or injury rather than age-related deterioration (and that they are not subject to the Hayflick limit).
