Biography

Jurōjin, the Japanese god of longevity, one of the Seven Lucky Gods

Longevity myths are traditions about long-lived people (generally supercentenarians), either as individuals or groups of people, and practices that have been believed to confer longevity, but for which scientific evidence does not support the ages claimed or the reasons for the claims. While literal interpretations of such myths may appear to indicate extraordinarily long lifespans, many scholars believe such figures may be the result of incorrect translation of numbering systems through various languages coupled with the cultural and/or symbolic significance of certain numbers.

The phrase "longevity tradition" may include "purifications, rituals, longevity practices, meditations, and alchemy" that have been believed to confer greater human longevity, especially in Chinese culture.

Modern science indicates various ways in which genetics, diet, and lifestyle affect human longevity. It also allows us to determine the age of human remains with a fair degree of precision.

Outside of mythology, the record for the maximum verified lifespan in the modern world is 122+12 years for women (Jeanne Calment) and 116 years for men (Jiroemon Kimura). Some scientists estimate that in case of the most ideal conditions people can live up to 127 years. This does not exclude the theoretical possibility that in the case of a fortunate combination of mutations there could be a person who lives longer. Though the lifespan of people is one of the longest in nature, there are animals that live longer. For example, some individuals of the Galapagos tortoise are able to live more than 175 years, and some individuals of the bowhead whale more than 200 years. Some scientists cautiously suggest that the human body can have sufficient resources to live up to 150 years.

Extreme longevity claims in religion

Hebrew Bible (Old Testament)

Several parts of the Hebrew Bible, including the Torah, Joshua, Job, and Chronicles, mention individuals with very long lifespans, up to the 969 years of Methuselah.

Some apologists explain these extreme ages as ancient mistranslations that converted the word "month" to "year", mistaking lunar cycles for solar ones: this would turn an age of 969 years into a more reasonable 969 lunar months, or about 78.3 solar years.

Donald Etz says that the Genesis 5 numbers were multiplied by ten by a later editor. These interpretations introduce an inconsistency: it would mean that the ages of the first nine patriarchs at fatherhood, ranging from 62 to 230 years in the manuscripts, would then be transformed into an implausible range such as 5 to 18+12 years. Others say that the first list, of only 10 names for 1,656 years, may contain generational gaps, which would have been represented by the lengthy lifetimes attributed to the patriarchs. Nineteenth-century critic Vincent Goehlert suggests the lifetimes "represented epochs merely, to which were given the names of the personages especially prominent in such epochs, who, in consequence of their comparatively long lives, were able to acquire an exalted influence".

Those biblical scholars that teach literal interpretation give explanations for the advanced ages of the early patriarchs. In one view, man was originally to have everlasting life, but as sin was introduced into the world by Adam, its influence became greater with each generation and God progressively shortened man's life. In a second view, before Noah's flood, a "firmament" over the earth (Genesis 1:6–8) contributed to people's advanced ages. The Bible's own (brief) explanation for these ages approaches the question from a different angle, explaining instead the relative shortness of normal lives in Genesis 6:3 (CSB): "And the Lord said, “My Spirit will not remain with mankind forever, because they are corrupt. Their days will be 120 years.”"

Christianity

  • Scolastica Oliveri is said to have lived in Bivona, Italy, 1448–1578 (age 129–130), according to the archive of Monastero di San Paolo in Bivona located in Palermo.

Chapter 2 of Falun Gong by Li Hongzhi (2001) states, "A person in Japan named Mitsu Taira lived to be 242 years old. During the Tang Dynasty in our country, there was a monk called Hui Zhao [慧昭, 526–815] who lived to be 290 [288–289] years old. According to the county annals of Yong Tai in Fujian Province, Chen Jun [陈俊] was born in the first year of Zhong He time (880 AD) under the reign of Emperor Xi Zong during the Tang Dynasty.

Egypt

The Egyptian historian Manetho, drawing upon earlier sources, begins his Egyptian king list with the Graeco-Egyptian god Hephaestus (Ptah) who "was king for 10,000 years".

Greece

A book Macrobii ("Long-Livers") is a work devoted to longevity. It was attributed to the ancient Greek author Lucian, although it is now accepted that he could not have written it. Most examples given in it are lifespans of 80 to 100 years, but some are much longer:

  • Tiresias, the blind seer of Thebes, over 600 years.
  • Nestor, over 300 years.
  • Members of the "Seres" (a Chinese people), over 300 years.

According to one tradition, Epimenides of Crete (7th, 6th centuries BC) lived nearly 300 years.

Japan

Some early emperors of Japan are said to have ruled for more than a century, according to the tradition documented in the Kojiki, viz., Emperor Jimmu and Emperor Kōan.

  • Emperor Jimmu (traditionally, 13 February 711 BC – 11 March 585 BC) lived 126 years according to the Kojiki. These dates correspond to 125 years, 339 days, on the proleptic Julian and Gregorian calendars. However, the form of his posthumous name suggests that it was invented in the reign of Kanmu (781–806), or possibly during the time in which legends about the origins of the Yamato dynasty were compiled into the Kojiki.
  • Emperor Kōan, according to Nihon Shoki, lived 137 years (from 427 BC to 291 BC).
  • Amakuni the inventor of Japanese sword Tachi was born in 7th century, and is said to be still alive, because he gained immortality, through to the amount of the swords he had invented and created.

Korea

  • Dangun, the first ruler of Korea, is said to have been born in 2333 BCE and to have died in 425 BCE at the age of 1,908 years.
  • Taejo of Goguryeo (46/47 – 165) is claimed to have reigned in Korea for 93 years beginning at age 7. After his retirement, the Samguk Sagi and Samguk Yusa give his age at death as 118, while the Book of the Later Han states he died in 121 at age 74.

Persian empire

The reigns of several shahs in the Shahnameh, an epic poem by Ferdowsi, are given as longer than a century:

  • Zahhak, 1,000 years.
  • Jamshid, 700 years.
  • Fereydun, 500 years.
  • Askani, 200 years.
  • Kay Kāvus, 150 years.
  • Manuchehr, 120 years.
  • Lohrasp, 120 years.
  • Goshtasp, 120 years.

Ancient Rome

In Roman times, Pliny wrote about longevity records from the census carried out in 74 AD under Vespasian. In one region of Italy many people allegedly lived past 100; four were said to be 130, others up to 140.

Sumer

  • Abzu, The Sumerian god is said to really exist, and he is really immortal, and he has lived for infinite and indefinite age.
  • Anu, the Sumerian god is said to really exist, and he is really immortal, and he has lived for longer time than the world exists.
  • Enki, the Sumerian god is said to really exist, and he is really immortal, and he as lived from the Creation of the world.

Age claims for the earliest eight Sumerian kings in the major recension of the Sumerian King List were in units and fractions of shar (3,600 years) and totaled 67 shar or 241,200 years.

In the only ten-king tablet recension of this list three kings (Alalngar, [...]kidunnu, and En-men-dur-ana) are recorded as having reigned 72,000 years together. The major recension assigns 43,200 years to the reign of En-men-lu-ana, and 36,000 years each to those of Alalngar and Dumuzid.

Sweden

  • Anna Persdotter was said to have born in 665 and have died in 1689 in 1,024 years of age.

Vietnam

  • Lạc Long Quân reigned from 2793 BC to 2524 BC (about 269 years).

Medieval era

Poland

  • Piast Kołodziej, king of Poland, died in 861 at the alleged age of 120 (740 AD/861 AD).

Wales

  • Welsh bard Llywarch Hen (Heroic Elegies) died c. 500 in the parish of Llanvor, traditionally about age 150.

England

  • Edgar Ætheling, English prince who was briefly King of England after the death of Harold Godwinson at the Battle of Hastings in late 1066. Edgar is said to have died shortly after 1126, when William of Malmesbury wrote that he "now grows old in the country in privacy and quiet". However, two pipe rolls exist from the years 1158 and 1167 which list Edgar. The historian Edward Augustus Freeman stated that this referred either to Edgar (aged at least 115), to a son of his, or to another person who bore the title Ætheling.

Modern extreme longevity claims

This list includes claims of longevity of 130 and older from the 14th century onward. All birth year and age claims are alleged unless stated otherwise.

NameBirthDeathAgeCountrySummary
Li Ching-Yuen1736 - claimed

1677 - disputed

1933196–197
255–256
Qing Dynasty,
Republic of China
A New York Times story announced the death on 5 May 1933 in Kai Xian, Sichuan, at the age of 197, of the Republic of China's Li Ching-Yuen (李青云, Li Qing Yun), who claimed to be born in 1736. A Time article noted that "respectful Chinese preferred to think" Li was 150 in 1827 (birth 1677), based on a government congratulatory message, and died at age 256. T'ai chi ch'uan master Da Liu stated that Li learned qigong from a hermit over age 500.
Peter Czartan15391724184HungaryCharles Hulbert, who reported Czartan's case in an 1825 collection, added that John (172) and his wife Sara (164) both died in Hungary in 1741 after 148 years of marriage. The Book Validation of Exceptional Longevity has the old couples last name as Rowin, while The Virgin Birth And The Incarnation puts John and Sara's married name as Rovin.
Henry Jenkins15011670169EnglandA brief biography of Henry Jenkins, of Ellerton-on-Swale, Yorkshire, was written by Anne Saville in 1663 based on Jenkins's description, stating birth in 1501; he also claimed to recall the 1513 Battle of Flodden Field. However, Jenkins also testified in 1667, in favor of Charles Anthony in a court case against Calvert Smythson, that he was then only 157 or thereabouts. He was born in Bolton-on-Swale, and the date given, 17 May 1500, results in only a 1-year discrepancy with the age of 169 on his monument (he died 8 December 1670).
Shirali Muslimov18051973168Russian Empire,
Soviet Union
An Azerbaijani shepherd of Talysh ethnicity from the village of Barzavu in the Lerik region of Azerbaijan, a mountainous area near the Iranian border. He claimed to be the oldest person who ever lived when he died on September 2, 1973 at the alleged age of 168 years and 162 days, based solely on a passport. National Geographic carried the claim. Some sources claimed him to be the oldest centenarian in the USSR. It was reported that at the moment of Muslimov's death, his wife was still living at 120 years of age.
Javier Pereira17891955–58165–169ColombiaA Zenú Indian from Colombia who was reputedly over 160 years old at the time of his death. Although his death is variously said to have been in 1955, 1956, and 1958, sources all claim that he was born in 1789.
Zaro Aga17641934170Ottoman EmpireKurdish man who claimed birth on February 16, 1764, and died on June 29, 1934 in Istanbul, Turkey at the alleged age of 170.
Thomas Parr1482–14831635152EnglandThe case was recorded in Philosophical Transactions of the Royal Society. William Harvey carried out a postmortem on him, according to Easton. Parr is buried in Westminster Abbey with his alleged age on the gravestone.
Mbah Gotho 18702017146Dutch East Indies,
Indonesia
In May 2010, Solopos reported that census enumerators recorded that Saparman Sodimejo, known more commonly as Mbah Gotho, was 142 years old. Liputan 6 reported that his estimated age was 140, and that he could not remember his date of birth but claimed to remember the construction of a sugar factory in Sragen in 1880. His ID card, issued in 2014, displays his claimed birth date of 31 December 1870. A heavy smoker throughout his life, he allegedly outlived ten siblings, four wives and all five of his children. On 28 April 2017 he was admitted to RSUD Hospital in Sragen, where he died on 30 April.
Bir Narayan Chaudhary 18561998141–142NepalBir claimed he was born in 1856, the son of a landowner. A cattle rancher in the village of Khanar, near Biratnagar, he was purportedly a leader of the first land survey team in the area, conducted in 1888. He was a smoker throughout his later life. Bir rose to prominence in the mid-1990s when Nepalese television and press began reporting on his claimed age. In 1997, he was honored by Nepal's King Birendra for his claimed longevity.
Mubarak Rahmani Messe18742014140AlgeriaDied in 2014, allegedly at 140 years of age, in El Oued Province, Algeria, and was survived by 100 grandsons. According to family members, Rahmani had spent much of his early life in the Algerian Desert and later held various challenging occupations, including in construction, farming and herding. He was hospitalised for the first time in 2012, with a stomach complaint. His diet, referred to as "natural", consisted largely of dates, wheat flour, sheep's milk, and green tea.
Habib Miyan 18692008138IndiaRahim "Habib Miyan" Khan of Jaipur, Rajasthan, India, holds the Guinness World record for the Longest retirement pension. Miyan's claimed birth date derives from a family tree listing a Rahim Khan born in 1869, although his pension book listed his birth date as May 20, 1878. He said he had been using these documents since he was discharged from the army in 1938 to claim a pension, making him the world's longest-registered old-age pensioner. The Limca Book of Records lists him as the oldest man of Jaipur, describing him in its 2005 edition as "over 120 years". In 2004 two unidentified people donated money for Miyan to go to the Hajj, making him purportedly the oldest Hajj pilgrim in history. He was named as the Aab-e-Jaipur, ('Lustre of Jaipur') by the mayor of Jaipur.
Charlie Smith18421979136–137United StatesPrior to Smith's death, the Guinness Book of World Records had called his claim into question, noting that Smith's marriage certificate from 1910 stated that he was 35 years old at the time, which would make him 104 years old at the time of his death.

  • The Assamese polymath Sankardev (1449–1568) allegedly lived to the age of 118.
  • Albrecht von Haller allegedly collected examples of 62 people ages 110–120, 29 ages 120–130, and 15 ages 130–140.
  • A 1973 National Geographic article on longevity reported, as a very aged people, the Burusho–Hunza people in the Hunza Valley of the mountains of Pakistan.
  • Swedish death registers contain detailed information on thousands of centenarians going back to 1749; the maximum age at death reported between 1751 and 1800 was 147.
  • Cases of extreme longevity in the United Kingdom were listed by James Easton in 1799, who covered 1712 cases documented between 66 BC and 1799, the year of publication; Charles Hulbert also edited a book containing a list of cases in 1825.
  • A periodical The Aesculapian Register, written by physicians and published in Philadelphia in 1824, listed a number of cases, including several purported to have lived over 130. The authors said the list was taken from the Dublin Magazine.
  • Deaths officially reported in the Russian Empire in 1815 listed 1068 centenarians, including 246 supercentenarians (50 at age 120–155 and one even older). Time magazine considered that, by the Soviet Union, longevity had elevated to a state-supported "Methuselah cult". The USSR insisted on its citizens' unrivaled longevity by claiming 592 people (224 male, 368 female) over age 120 in a 15 January 1959 census and 100 citizens of the Russian SSR alone aged 120 to 156 in March 1960. According to the opinion of Time magazine, in Georgia such claims were fostered by Georgian-born Joseph Stalin's apparent hope that such longevity might rub off on him. Zhores A. Medvedev, who demonstrated that all 500-plus claims failed birth-record validation and other tests, said that Stalin "liked the idea that [other] Georgians lived to be 100".
  • An early 1812 Russian Petersburgh Gazette reports a man between ages 200 and 225 in the diocese of Ekaterinoslaw (now Dnipro, Ukraine).

Practices

Diets

The idea that certain diets can lead to extraordinary longevity (ages beyond 130) is not new. In 1909, Élie Metchnikoff believed that drinking goat's milk could confer extraordinary longevity. The Hunza diet, supposedly practiced in an area of northern Pakistan, has been claimed to give people the ability to live to 140 or more, but such claims are regarded as apocryphal.

Alchemy

Traditions that have been believed to confer greater human longevity include alchemy.

  • Nicolas Flamel (early 1330s – c. 1418) was a 14th-century scrivener who developed a reputation as alchemist and creator of an "elixir of life" that conferred immortality upon himself and his wife Perenelle. His arcanely inscribed tombstone is preserved at the Musée de Cluny in Paris.
  • Fridericus (Ludovicus) Gualdus (Federico Gualdi [it]), author of "Revelation of the True Chemical Wisdom", lived in Venice in the 1680s. His age was reported in a letter in a contemporary Dutch newspaper to be over 400. By some accounts, when asked about a portrait he carried, he said it was of himself, painted by Titian (who died in 1576), but gave no explanation and left Venice the following morning. By another account, Gualdus left Venice due to religious accusations and died in 1724. The "Compass der Weisen" alludes to him as still alive in 1782 and nearly 600 years old.

Fountain of Youth

The Fountain of Youth reputedly restores the youth of anyone who drinks of its waters. Herodotus attributes exceptional longevity to a fountain in the land of the Ethiopians. The lore of the Alexander Romance and of Al-Khidr describes such a fountain, and stories about the philosopher's stone, universal panaceas, and the elixir of life are widespread.

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 on the expedition that led to the European discovery of Florida.
