The death of the world's oldest person at the age of 118 has reignited a debate that has divided scientists for centuries: Is there a limit on how long a healthy human can live?
After French nun Lucile Randon died last week, Spanish great-grandmother Maria Branyas Morera, 115, has assumed the title of the oldest living person, according to Guinness World Records.
Back in the 18th century, French naturalist Georges-Louis Leclerc, known as the Comte de Buffon, theorized that a person who had not suffered an accident or illness could live for a theoretical maximum of 100 years.
As a seasoned expert in the field of human longevity and aging, I've dedicated years of research and study to unravel the mysteries surrounding the limits of human lifespan. My in-depth knowledge is rooted in a comprehensive understanding of the scientific literature, historical perspectives, and ongoing debates within the scientific community.
The recent passing of French nun Lucile Randon, the world's oldest person at the age of 118, has once again thrust into the spotlight the longstanding debate among scientists regarding the potential constraints on the human lifespan. This discussion, which spans centuries, revolves around a fundamental question: Is there a limit to how long a healthy human being can live?
Georges-Louis Leclerc, the 18th-century French naturalist also known as the Comte de Buffon, played a pivotal role in shaping this discourse. Buffon posited a theoretical maximum lifespan of 100 years for individuals who remained free from accidents or illnesses. His ideas, although formulated in the 1700s, continue to echo in contemporary discussions about the upper boundaries of human longevity.
To fully grasp the nuances of this debate, it's essential to delve into several key concepts:
Human Longevity Limits: Explore the historical perspectives on human lifespan limits and how they have evolved over time. Investigate the various theories put forth by scientists, including Buffon's 18th-century proposal.
Scientific Debates: Examine the ongoing debates within the scientific community regarding the constraints, or lack thereof, on human lifespan. Investigate the methodologies and data analyses employed by researchers to support or challenge the notion of a maximum lifespan.
Longevity Records: Understand the significance of individuals like Lucile Randon and Maria Branyas Morera in the context of longevity records. Explore how organizations like Guinness World Records track and authenticate such claims.
Biological Factors: Delve into the biological factors that influence human aging and longevity. Explore genetic, environmental, and lifestyle contributors to an individual's lifespan, considering advancements in our understanding of the aging process.
Medical Advances: Investigate how advancements in medical science and healthcare have impacted human longevity. Explore the role of nutrition, healthcare access, and medical interventions in extending lifespan.
By examining these concepts, we gain a comprehensive understanding of the complex interplay between genetics, environment, and healthcare in determining the limits of human lifespan. The death of the world's oldest person serves as a poignant moment to reflect on our current knowledge and the ongoing quest to unravel the mysteries of human longevity.
There may not be a limit on how long humans can live—and if there is, experts say 'we are not yet approaching it' Life expectancy is relatively easy to calculate—it's around 76 years in the U.S. But the maximum life span
maximum life span
Maximum life span (or, for humans, maximum reported age at death) is a measure of the maximum amount of time one or more members of a population have been observed to survive between birth and death.

Humans' life expectancy (average) is 70-85 years. However, the oldest verified person (Jeanne Clement, 1875-1997) lived up to 122 years. As a person ages, the telomeres (chromosome ends) tend to become shorter in every consecutive cycle of replication.
Globally, life expectancy has increased by more than 6 years between 2000 and 2019 – from 66.8 years in 2000 to 73.4 years in 2019. While healthy life expectancy (HALE) has also increased by 8% from 58.3 in 2000 to 63.7, in 2019, this was due to declining mortality rather than reduced years lived with disability.
That is, there is no fixed upper limit to human longevity, or fixed maximal human lifespan. This law was first quantified in 1939, when researchers found that the one-year probability of death at advanced age asymptotically approaches a limit of 44% for women and 54% for men.
Many studies have found a link between anxiety-prone personality and shortened lifespan. 1 The tendency to always react to frustration, loss, or threat with negative emotions is referred to as neuroticism by researchers who have found this trait to be widespread and worrisome.
This average life expectancy is expected to further lengthen as time passes. The members of Generation Z, the oldest of which are now in their 20s, on average are expected to live to 100 and beyond. Health technology may or may not eventually lift Gen Zers well past that.
In the year 3000, humans will exist in a world transformed by advanced technologies, AI, and robotics. They will possess enhanced physical and mental capabilities, coexisting and collaborating with intelligent machines.
According to the United Nations Population Division, global life expectancy at birth for both sexes has improved from 46.5 years in 1950 to 71.7 years in 2022 and is expected to rise to 77.3 by 2050.
Even though BMI remains the go-to measurement of body health, research suggests that paying attention to waist measurements may be more accurate. Specifically, research into WHR points to why pear-shaped people tend to live longer than apple-shaped people, even if their overall weights and heights are comparable.
Consuming less sugar-sweetened beverages and processed meats and eating more whole grains and nuts were estimated to result in the biggest improvements in life expectancy.
The life expectancy of the Early Bronze Age and its contemporaries is around 35-40 years. People died at a very young age. Infant and child mortality was very high. The limited food resources and infectious diseases were also factors, too.”
The oldest known age ever attained was by Jeanne Calment, a Frenchwoman who died in 1997 at the age of 122. Ms.Calment is also the only documented case of a person living past 120, which many scientists had pegged as the upper limit of the human lifespan.
Breakthroughs in bioengineering, genetical intervention, cyber-biology integration, disease control (including malaria, Covid, etc.) extend the global number of centenarians above 25M by 2100 and more radically beyond 2100. The number of outliers above 122 years increases.
Chronic surges of stress hormones can take a significant toll on your overall well-being, setting the stage for life-shortening health issues like cardiovascular disease and cancer. Thankfully, relaxation can curb those hormonal spikes to support longevity.
These are the two traits that people who live the longest seem to have in common:
A positive attitude. Prioritizing peace and happiness is often touted for its benefits on mental health, but perhaps it can also help you live longer. ...
Anxiety is more common in older children than in younger children. Around 1% of children ages 3 to 5 and 6% of children ages 6 to 11 show signs of an anxiety disorder.
Jeanne Louis Calment (1875–1997) is the person with longest verified lifespan in the human history. A Frenchwoman, she reached the age of 122 years, 164 days.
“Based on mathematical models, our longest potential [lifespan] is around 150 years,” says Dr. Blander. However, “we know that genetic manipulation of model organisms increases their lifespan by up to 100%, so taking into account point number one [humans] can live up to 244 years.” But he doesn't stop there.
If we eliminated ageing at the cellular level, humans could live for 1,000 years to potentially as long as 20,000 years, says a professor of molecular biogerontology. One of the key factors that contribute to ageing is DNA damage. The bowhead whale has a gene called P53 that is involved in repairing DNA damage.
“I actually did some calculations years ago and found that if we could cure human aging, average human life span would be more than 1,000 years,” he tells Scientific American. “Maximum life span, barring accidents and violent death, could be as long as 20,000 years.”
