How long can humans live?

Reflexes

  • If we eliminated aging at the cellular level, humans could live between 1,000 and potentially up to 20,000 years, says a professor of molecular biogerontology.
  • One of the key factors contributing to aging is DNA damage. The bowhead whale has a gene called P53 that is involved in repairing DNA damage.
  • Magalhães’ theory of eliminating aging at the cellular level means that we must target certain genes that control the aging process, cell death, DNA repair and metabolism.

One of the most outspoken proponents of the idea that humans could live for thousands of years is João Pedro de Magalhães, a professor of molecular biogerontology at the University of Birmingham in England. Magalhães has studied the genomes of very long-lived animals, such as the Greenland whale (which can reach 200 years) and the naked mole rat (which can live up to 30 years, an extraordinary lifespan for a rodent).

Based on his research, Magalhães believes that humans could live 20,000 years if we managed to eliminate aging at the cellular level. He argues that the aging process is caused by a number of factors, including DNA damage, the buildup of senescent cells, and the deterioration of the immune system. If we could find ways to prevent or repair this damage, then we could extend human life indefinitely.

What is the current maximum human life expectancy?

Jeanne Calment

The maximum human life expectancy recorded to date is 122 years. This is how old Jeanne Calment, a French woman and super-centenarian, was when she died in 1997. Calment was the oldest verified human to have lived to be 122 according to Guinness World Records and the Gerontology Research Group.

Who is called a supercentenarian?

A supercentenarian is a person who has turned 110 years old. The word “supercentennial” comes from the Latin words “super” (meaning “above”) and “centenario” (meaning “one hundred years”).

Can humans live that long? Yeah.

Magalhães’ theory on the elimination of aging at the cellular level is based on the idea that aging is programmed in our cells. This means that we need to target certain genes that control the aging process, cell death, DNA repair, and metabolism.

But how is it possible?

In recent years there have been some promising advances in the field of anti-aging research. For example, scientists have identified a number of genes involved in the aging process and are working to develop drugs that can target these genes. Although the technology is yet to be created.

Magalhães cites research on rapamycin, a drug that has been shown to prolong life in mice, as evidence that it may be possible to achieve this goal.

Magalhães’ research is also based on the study of very long-lived animals, such as the bowhead whale (estimated to live more than 200 years) and the naked mole-rat (which can live 30 years, while similar rodents live less). ). These animals have evolved to be extremely resistant to aging and can live hundreds or even thousands of years.

Magalhães believes that by studying these animals we can learn to prolong human life in a similar way. Listen to an excerpt from his TEDx talks on how we can manipulate aging.

Let’s move on to the burning question.

How long can humans really live?

“We could live for a millennium. If we eliminate aging at the cellular level, humans could live between 1,000 years and potentially up to 20,000 years.” -Magalhaes

However, one of the key factors that contribute to aging is DNA damage. When DNA is damaged, it can cause mutations that can eventually cause cancer. But bowhead whales “seem to have much better DNA repair,” Magalhães said.

The bowhead whale has a gene called P53 that is involved in repairing DNA damage. This gene is also found in humans, but it is not as active. If we could find ways to increase the activity of P53 in human cells, then we could extend human lifespan.

Magalhães also believes there may be other genes involved in the bowhead whale’s long lifespan. He cites that if we could target these genes to slow cell growth and metabolism in humans, then we could potentially extend human lifespans.

So all that is needed is to modify our genetic code?

Yes. Although the idea that humans could live for thousands of years by modifying our genetic code is fascinating, it is important to note that this remains only a theoretical possibility. The future of human longevity is still uncertain, but research by João Pedro de Magalhães and others suggests that the human race could one day live for hundreds of years and, in some cases, thousands of years.
