Longevity and longevity are concepts related to biology and the evolution of the cells and organs that make up the bodies of living things and their changes over the course of their lives. In the case of human beings, longevity has important connections with demographic aspects of society and sociological aspects of the individual. It generally has to do with the lifespan of a human being or a biological organism and is most often used in reference to the old age or age of a living being, for example the longevity of a tree. Reflections on longevity are usually linked to the recognition of human brevity and include discussions of methods to extend it beyond the limit held to be normal. The subject has been not only a concern of science, but also of travel literature, science fiction, and utopian novels. It is quite difficult to find the person who has lived the longest, even with modern standardized verification techniques, due to inaccurate or incomplete dates of birth. Multiple legends in different cultures and religious contexts have claimed extraordinary longevity, such as that of Methuselah in the Bible who supposedly lived 969 years.


A statement by Diogenes Laerci (c. 250) is the oldest reference to a plausible centennial longevity accepted by science. Diogenes stated that the astronomer Hipparchus of Nicaea (185 BC - 120 BC) claimed that the philosopher Democritus of Abdera had lived 109 years (he was born approximately between 470 BC and 460 BC and died between 370 BC and 360 BC). Other references to other thinkers of Greek antiquity corroborate the fact that Democritus had lived more than a hundred years. The possibility that this is true is also supported by the fact that most philosophers in ancient Greece lived more than 90 years. Some examples: Xenophanes of Colophon, a. 570/565 - a. 475/470 B.C. Pirró d'Elis, c. 360 - a. 270 B.C. Eratosthenes of Cyrene, a. 285 - a. 190 BC But the case of Democritus is different from that of, for example, Epimenides of Crete (lived between the seventh and sixth centuries BC) which is referenced even by thinkers of the last century, who is said to have lived 154, 157 and even 290 years, a case that has not been verified by science.

Life expectancy

Life expectancy is the average number of years that a certain population lives in a certain period. It is usually divided into male and female, and is influenced by factors such as the quality of medicine, hygiene, wars, etc., although currently it is usually referred only to people who have a nonviolent death. Life expectancy as a social indicator is used by sociologists to measure a country’s degree of development, but data can be altered by wars, epidemics, violence, and other phenomena other than economic indicators. In many cases people from underdeveloped or developing countries or isolated cultures may have a long longevity that contradicts the assumption that the higher the development, the longer the life expectancy.

The most people in history

People over the age of one hundred are usually not only of scientific interest, but also of the general public, interested in prolonging their life years in a healthy way. The Gerontological Research Group, founded between 1990 and 1992 in Los Angeles, is looking for people who are over 110 years old and is responsible for documenting people Eilif Philipsen (1682–1785, 102 years and 333 days): is the first person to reach 100, 101 and 102 years (July 21) whose age could be validated. Geert Adriaans Boomgaard (1788–1899, 110 years and 135 days): is the first person to reach the age of 110 (September 21, 1898) to whom age
