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, if one exists, is much harder to estimate, experts say.
Interestingly, we found Neanderthals and Denisovans, which are extinct species closely related to modern humans, had a maximum lifespan of 37.8 years. Based on DNA, we also estimated a “natural” lifespan modern humans of 38 years. This matches some anthropological estimates for early modern humans.
Using the human genome, the researchers found that the maximum natural lifespan of humans is 38 years, which matches anthropological estimates of lifespan in early modern humans. They found Neanderthals and Denisovans had a maximum lifespan of 37.8 years, similar to modern humans living around the same time.
These are natural changes that occur while aging. They cannot be stopped but it is possible to slow the rate of these processes. This can be done by changing one's lifestyle (diet, exercise, etc). The science of aging is not yet fully understood; therefore, it is difficult to determine an absolute limit of 200 years.
So, biology says that the maximum human life expectancy is somewhere around 97 years, but there is a twist: Humans seem to be unusual.
Scientists have found a way to lengthen worms' lives so much, if the process works in humans, we might all soon be living for 500 years. They've discovered a "double mutant" technique, when applied to nematode worms, makes them live five times longer than usual.
And although a human's average life expectancy has increased by decades in the last 100 years or so, our maximum life span hasn't shifted anywhere near as significantly. Many biologists think extending human life to that degree is currently impossible.
Age gap. Some scientists believe that within the next few decades, it could be possible for humans to live 1,000 years or more. Normally, as time passes, our cells undergo changes: Our DNA mutates, cells stop dividing, and harmful junk—by-products of cellular activity—builds up.
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.
By preventing cells from reaching senescence one can achieve biological immortality; telomeres, a "cap" at the end of DNA, are thought to be the cause of cell aging. Every time a cell divides the telomere becomes a bit shorter; when it is finally worn down, the cell is unable to split and dies.
The answer, it turns out, may lie in the meaty diets of their early human ancestors and the evolution of genes that protected them from the many hazards of carnivory.
Meet Hinat, a Nabataean woman who lived 2,000 years ago in what is now Saudi Arabia.
In 7 years, humans might be able to live indefinitely, predicts Ray Kurzweil, a futurist with a track record of accurate predictions. He believes that with the technological advances and expansions, we're witnessing today in genetics, robotics, and nanotechnology; we'll soon have nanobots running through our veins.

AI-Based Research Suggests , Reversing Human Age , May Be 'Biologically Impossible'. New research suggests that the process of aging can potentially be slowed but not reversed.
Life was very different for human societies 20,000 years ago. Humans hunted animals for food and had just started living in settlements. Unfortunately, very little evidence from this period exists.
The current record for human lifespan is held by Jeanne Calment, who lived to be 122 years and 164 days old. While this is an impressive achievement, it is still far from the 300-year mark. In fact, there is currently no scientific evidence to suggest that it is possible for humans to live for such a long time.
It might be hard to imagine, but it's true: As of today, if you are 35 years old or younger it is quite probable you will live to the see the year 2100 and witness the beginning of the 22nd century.
The researchers forecast that by 2050 life expectancy for females will rise to 89.2-93.3 years and to 83.2-85.9 years for males. The U.S. Census Bureau and the Social Security Administration project life expectancy in 2050 of 83.4-85.3 years for females and 80.0-80.9 years for males.
Yes, almost certainly, but the factors that determine the outcome are so immensely complex that our blunt and instrumental efforts are almost meaningless. The only thing that makes a difference is the combined impact of all individual animals including humans.
The average life expectancy of baby boomers, Gen X, Millennials, and Gen Z are different. Compared to the 70-year life expectancy of baby boomers and the 85-year life expectancy of Gen X, Gen Z is predicted to have a life expectancy of over 100 years.
Today, oxygen makes up roughly 21 per cent of our air, but it was virtually non-existent in Earth's early atmosphere. Soon after the advent of photosynthesis 2.4 billion years ago, oxygen levels crept up to 1 or 2 per cent – if you were to breathe this air, you would die almost immediately.
