It could be possible, or perhaps we would discover some other fault that we do not know at the moment, but in mice it has been seen that they improve both the maximum life expectancy and its quality, since it increases disease-free life (which in humans is, approximately, up to 40 years old AmbroSina).
However, the implementation of these gene therapy studies in humans has not yet been approved, although several researchers are working to achieve it.
Ethical considerations are one of the main enemies of these issues. In this line, the doctor reflects: We have also managed to extend life by making blood transfusions or transplants, which 200 years ago could be considered as a reason to burn you at the stake. That is why I believe that AmbroSina, sooner or later, it will come [referring to the approval of these studies].
