How long can people live in a real world?

If you can only reach 105, the survival probability seems to have a 50/50 level each consecutive year of life. This is broadly agreed upon by many scientists. One of the eldest controversies in the longevity study nevertheless is if this statistic curiosity indicates a real "mortality plateau," which means that the time one of us may hang around is almost unlimited.

"Death rates, which exponentially rise up to around 80, slow afterward and reach or approach the plateau after 105 years," the scientists in a 2018 publication stated re-entering the protracted discussion about the prospect of immortality.

Jean-Marie Robine, a demographer at the French Institut for Health and Medical Research then, said: 'If there is a dying plateau, then there is no limitation to the longevity of fellow humans.'

However, the most recent study into the subject indicates that all of us have a practical shelf life, a maximum lifetime not much longer than the highest reported date of expiration of Jeanne Calment, of France, who died at 122 years of age in 1997.

Here's what's almost 100% sure...

The current study focuses on statistics, therefore please allow me: 95,000 Centennials (100+ individuals) were present in 1990. Thanks, both to an increasing population and to health advances, the figure is predicted to rise to 451,000 by 2015, to 3.7 million by 2050.

Sheer chances suggest that when more people do so in life, someone is going to take it more and set a new record, experts recently found in Demographic Research newspaper. Sometime in this century, the record of Calment will collapse, scientists, say with almost 100% certainty. They also set chances that somebody could live till the mature age of...

124: 99%

127: 68%

130: 13%

135: “extremely unlikely”

"The data implies that people who have survived to the age of 110 are quite different from others," says Michael Pearce, the study's primary writer, a statistics student at the University of Washington. 'In a surprise, their annual mortality rates remain high yet constant after 110 years, irrespective of any other features like as sex and nationality.'

Pearce has studied data on super-centennials in the USA, Canada, Japan, and 10 European countries with his UW co-worker Adrian Raftery, Ph.D., professor of sociology and statistics.

"It's all the many things life throws on you, like illness," adds Raftery. " They die for reasons unrelated to younger generation concerns. This is a really robust, exclusive group of people".

Aging is something humorous since...

If evolution chooses to survive and reproduce, you could hope to find ways to keep us young and vitally important for all eternity. But instead, cells across our bodies stop dividing and performing the work, a process which we call senescence, gradually.

The theory says that natural selection does not work as well as we grow older to explain that apparent paradox. Maybe all the mutations and injuries that we amass in our cells can not be addressed indefinitely and/or selection for youth is inherently related to an afterthought of adverse effects.

The obvious issue then is: can the pace of aging be slowed down or prevented if the hurdle to immortality is the natural aging of our cells?

Scientists have recently examined the relationship between life span (what is conceivable) and life expectancy to help answer this question (how long people live on average, a figure that has increased considerably over the past century). They looked at the evidence from human history as well as certain of our primate relatives, gorillas, baboons, and chimpanzees. Their conclusion is published in the Nature Communications journal:

'The pace of aging for a species is generally stable' explains Susan Alberts, a member of Duke University's study team, Ph.D., Professor of Biology and Evolutionary Anthropology. "Populations are growing older because more people are getting older. Early life was extremely perilous for humans, while now most early deaths are prevented."

Whatever the number of vitamins you consume...

We cannot possibly escape biological limits completely by the aging rate, adds Alberts colleague Fernando Colchero, Ph.D., a University of Southern Denmark Associate Professor of Statistics.

"The inevitability of human death," adds Colchero. "We'll eventually age and die regardless of how many vitamins we take, how healthy our environment or how much we practice." Maybe the inevitable could be delayed a little longer, however. "Medical research has progressed at an unparalleled pace, he said, so that perhaps science can do what it can't achieve: reducing the aging rate."

Assuming that a miraculous cure aside, a lot of continuing research tries not merely to lengthen life but also to raise our collective health – the years that we have lived and are good – to slow or reverse cell death in certain organisms.

Pearce, the UW researcher, also opens the statistical door — always a little — to quite a few opportunities.

"Our research shows that there is no ultimate limit to longevity but a practical limit to it," he tells me. " Although for 150 or 200 years we continue to enhance everyone's potential, this is very, very unlikely..."
