The DNA of our cells is like a computer, it can perform many functions, but it needs a "keyboard", that is epigenetics. If it were a keyboard, it breaks down or gives false, erroneous instructions, that cell breaks down and ages, which What the latest study is pursuing is to improve that keyboard, to restore that keyboard back to a youthful state, in this way you can “back up” your healthy, youthful state.
Epigenetics is what orders what genes to activate, what works to activate here or what thing to turn off so that it does not work or when certain factors come into operation, that is what can be changed and thus rejuvenate the entire system, but to put live forever you would have to go inside the DNA and change the boundary.
Organ regeneration is also being experimented with, for example, imagine that someone has a liver problem instead of transplanting the liver, the possibility is being studied that healthy liver cells can regenerate the organ or insert new cells that regenerate that organ, it has been experimented with the liver and with the kidneys.
Stem cells are in line with regeneration, but epigenetics is more complex, it is more global, regeneration would affect specific organs, organs such as the liver, kidneys, and heart could be rejuvenated or regenerated; Deep down, this is what it seems to me, is that researchers do not pursue eternal life, they seek to be able to rejuvenate the body and reach an advanced age, but with a very healthy state that would be the objective.
Being able to reach 80 years of age, for example, but with a body of 30, would not mean eternal life, one could live much longer, the important thing is to eliminate all the ailments, diseases and disorders that are brought about and that go hand in hand with aging.
And I clarify, no matter how much modern treatment, or mastering epigenetics, no matter how many regeneration factors you apply and no matter how many treatments you do, researchers say that an unhealthy life, the consumption of drugs, alcohol, smoking or being exposed to contaminants will end up destroying any organism, no matter how many operations and systems are carried out.
Researchers aim not to live longer but to live longer in health, to extend the span of human health, the number of years a person stays not just alive, not just alive but healthy, in order to reach old age without suffering the health problems that come with aging, that would be the dream of these researchers.
Right now we are at the beginning of this technology, a lot of money is being invested as Jeff Bezos, the owner of Amazon, is doing, maybe we will see the real results in practice in 10 or 20 years, but when they are reached It's going to be an awesome change.
