Normally, as time passes, our cells undergo changes: Our DNA mutates, cells stop dividing, and harmful junk—by-products of cellular activity—builds up. All these processes together cause us to age.
Can humans live forever? While the population can expect to live longer lives on average, the human lifespan might have a cap. Scientists believe that the human lifespan could be anywhere from 120-150 years long, but not longer than that, due to accumulating hallmarks of aging and chronic disease.
While, as shown with creatures such as hydra and Planarian worms, it is indeed possible for a creature to be biologically immortal, these are animals which are physiologically very different from humans, and it is not known if something comparable will ever be possible for humans.
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.
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.
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.
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.
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.
More reproduction followed, and more mistakes, the process repeating over billions of generations. Finally, Homo sapiens appeared. But we aren't the end of that story. Evolution won't stop with us, and we might even be evolving faster than ever.
Scientists say humans could be just seven years away from achieving immortality - and finding a way to live forever. Computer scientist Ray Kurzweil says immortality could be possible by 2030, reports indy100.
To date, we have not been able to completely replicate all features of a human being in a robotic form. Walking, for example, has proved to be a very difficult human feature to replicate.
Predicting this timing is tricky, to say the least. But Kurzweil says one crucial step on the way to a potential 2045 singularity is the concept of immortality, possibly reached as soon as 2030. And the rapid rise of artificial intelligence is what will make it happen.
For men, the group expects they will live to be 83 to 86 instead of the government's projection of 80 years average life expectancy in 2050. S. Jay Olshansky, co-author of the report, said a few extra years life might not sound important, but it will cost us socially and financially.
According to one tradition, Epimenides of Crete (7th, 6th centuries BC) lived nearly 300 years.
In the next 1,000 years, the amount of languages spoken on the planet are set to seriously diminish, and all that extra heat and UV radiation could see darker skin become an evolutionary advantage. And we're all set to get a whole lot taller and thinner, if we want to survive, that is.
At the end of the study, about 16 percent of the men and about 34 percent of the women survived to the age of 90. In fact, the authors found that women who were taller than 5 feet 9 inches were 31 percent more likely to reach 90, compared to those who were under 5 feet 3 inches.
Japanese life expectancy
This low mortality is mainly attributable to a low rate of obesity, low consumption of red meat, and high consumption of fish and plant foods such as soybeans and tea. In Japan, the obesity rate is low (4.8% for men and 3.7% for women).
The World's Oldest Person Today: María Branyas Morera
María Branyas Morera is the current oldest living person in the world, as of April 2023.
The oldest person ever whose age has been verified is Jeanne Calment (1875-1997) of France, who lived to the age of 122.
Homo habilis, sometimes known as "handyman", was one of the oldest known humans and lived between 2.4 million and 1.4 million years ago in Eastern and Southern Africa.
The increased longevity of humans is, in part, attributable to environmental changes; improved food, water, and hygiene; reduced impact of infectious disease; and improved medical care at all ages.
Eventually humans will go extinct. At the most wildly optimistic estimate, our species will last perhaps another billion years but end when the expanding envelope of the sun swells outward and heats the planet to a Venus-like state. But a billion years is a long time.
