Immortality: can we delay the aging process indefinitely?

The aging of the body is an inevitable process of life no matter how hard you try to slow it down or even stop it. But that without counting the progress of science, which could make it possible to delay the deterioration of the cells of the organism … Researchers definitely believe in it as hard as iron. Yes but how ?

Researchers have been studying human or animal cells for years. But it wasn’t until the 1960s that the scientist Leonard Hayflick solved a riddle about the process of cell aging in humans. In fact, Hayflick discovered that a human cell can only divide about fifty times before it goes into a hibernation state known as “senescence”.

Researchers then theorized that it is the accumulation of these senescent cells that causes oxidative damage, or the appearance and accumulation of small defects in DNA. The cells then become less and less efficient. Hence the problems associated with old age (the body becomes fragile, the skin becomes wrinkled, etc.).

Attack the cells directly …

The idea of ​​some researchers would be to solve the problem directly in the cells by delaying their aging. Indeed, imagine that some cells are able to multiply to infinity. Please note that so far only cancer cells and those that have been genetically modified are capable of such benefits. Well, scientists plan to replicate the phenomenon on healthy human AND cells.

Understand the aging process

You have already tried the animal experiment and the results are very encouraging. For example, researchers have succeeded in overcoming the normal aging process of the nematode worm C. elegans. However, performing the same experiments on humans will not be easy, mainly for ethical reasons.

Indeed, Professor Janet Thornton, Anti-Aging Specialist at the European Institute for Bioinformatics, told Science Alert: “ [chez] Humans, it is unethical to mutate and there are so many conflicting forces at work that it is difficult to assess the implications. In the laboratory, the lifespan of worms can be multiplied by 10. […] However, an equivalent level is not available in humans. It is likely that the human system will be complex with many connections and buffers that these extensions may not be accessible. “”

This does not prevent researchers from working seriously on developing drugs to delay aging in humans. Some are already in clinical trials, but the results have not yet been published. Be continued.

With a few rare exceptions, aging is likely inevitable for all living things, although it can be delayed experimentally in animals. For “men”, the best way to delay aging is by eating a healthy, balanced diet and exercising regularly.
