We can't simply discard our old cells like hydra do, because we need them. For example, the neurons in the brain transmit information. However, his gut feeling is that humans will never achieve such biological immortality.
And so I think that people survive through their legacy. The oldest-living human on record is Jeanne Calment from France, who died at the age of in , according to Guinness World Records. In a study published in the journal Nature Communications , researchers reported that humans may be able to live up to a maximum of between and years, after which, the researchers anticipate a complete loss of resilience — the body's ability to recover from things like illness or injury.
To live beyond this limit, humans would need to stop cells from aging and prevent disease. Related: What's the oldest living thing alive today? Humans may be able to live beyond their biological limits with future technological advancements involving nanotechnology. This is the manipulation of materials on a nanoscale, less than nanometers one-billionth of a meter or billionths of an inch. Machines this small could travel in the blood and possibly prevent aging by repairing the damage cells experience over time.
Nanotech could also cure certain diseases, including some types of cancer, by removing cancerous cells from the body, according to the University of Melbourne in Australia. Preventing the human body from aging still isn't enough to achieve immortality; just ask the hydra. Even though hydra don't show signs of aging, the creatures still die.
Humans don't have many predators to contend with, but we are prone to fatal accidents and vulnerable to extreme environmental events, such as those intensified by climate change. We'll need a sturdier vessel than our current bodies to ensure our survival long into the future. The Resilience project of the Icahn School of Medicine is working to understand the hidden factors that keep people away from disease.

Subscribe to Weekly Newsletter :. The simplest way to do this would be by doing a brain transplant - which nobody knows how to do, though some partial brain transplants have happened in mice. Other ways to do this would be to "upload" your consciousness into the other brain.
That's something I find highly dubious, as I elucidated last summer. Even if it's possible, it's not going to happen in 20 years. Finally, in order to make this happen - you not only have to clone a person, accelerate the aging process, develop a means to switch consciousness from one to the other, but also turn our culture into something so morally callous that it's willing to grow disposable people who are the property of others.
Because make no mistake, that's what we're talking about here. A clone is a person - from a scientific perspective, pretty much the same as an identical twin. That clone would have rights, and people would have a moral obligation to protect those rights.
Frey goes on to some other equally scientifically dubious propositions, all of which boil down to the idea that we're just a handful of years away from developing immortality. There's a rather large collection of individuals on the Internet with the same belief, many of whom I've corresponded with. But there's no evidence to believe that we're even close of extending the life span of the average person to the age of , much less forever.
As of , the global average life expectancy was about 67 years old, and even in the most developed countries average life expectancy caps out at just a little over We still have a long way to go.
Some of such centenarians who are now alive are vegetarians, some eat a lot of meat and drink wine, some are smokers, many love chocolate, and many don't like to exercise. But what they do have in common is that they are generally happy and easy-going. And we think it's something to stick to while the scientists are busy trying to unlock the secret to immortality.
What do you think will happen in the future in this field? Do you believe science can really make people live forever? We'd love to hear your opinion in the comments! A great amount of money is being put forward for immortality research, and there are many celebrities who are involved in the contribution: Larry Ellison : one of the five richest men on Earth and one of the owners of Oracle.
Mitochondrial Mutations: components in our cells that are important for energy production. Intracellular Junk: proteins that are not properly "digested" by our cells.
Extracellular Junk: proteins accumulated outside the cells. For example, in the brains of Alzheimer's patients.
Cell Loss: cells that can't be regenerated by the body itself. Cell Senescence: when cells lose the ability to divide. Extracellular Crosslinks: cause the loss of elasticity in cells and tissues. Modern science on immortality and 5 ways to achieve it:.
