Life is too short and it goes by in a blink of an eye. Humans have always tried to find ways to expend their lifespan. As our civilization has evolved, we have developed medical technologies that permit us to cure disease and heal injuries, which as greatly increase the lifespan of humans. Other factors like good nutrition, regular exercise, hygiene and salubrity, and a decrease in violence, also increased the average life expectancy of humans. Nevertheless, we are still substantially far from the ancient quest, of the alchemists and their philosopher’s stone, to achieve immortality. All things considered, let’s probe into our imagination and examine the possible ways we could attain immortality.
Biological Immortality, also termed bio-indefinite mortality, is a state in which the mortality rate from senescence is stable, allowing the body to be free from chronological aging. There is a variety of unicellular and multicellular species that are able to support that state. Additionally there some species of lizards like salamanders that have regenerative properties like growing back severed limbs. So imagine that one day we would have access to rejuvenation clinics that would use genes of those different species to regenerate your old body making it young again and then slow down the aging process to permit you to live for a very long period of time.
Cloning facilities could be another option offered to us in the future. If eventually, we could find a way to transfer our consciousness into a new body, cloning could become one way to live forever. Basically, every time that you would get old or you would be about to die, you could get a transfer into a younger version of your self. Furthermore, we would need the implementation of a backup system, in case of accidental death, to restore your consciousness into one of your clones.
Transferring our consciousness into a machine. This third option is similar to the clone idea but instead, you would transfer your consciousness into a robotic body that could basically exist as long as you can maintain and replace broken parts. Also, those who can’t afford a robotic body, at the time of their death, could transfer their consciousness into a computer so their love ones could stay in touch with them in a virtual form.
Ultimately, immortality or prolonged lives will probably be extremely costly and only the rich people will have access to those technologies. So would it be a good thing? Should we have a limit on how long humans should live? I guess that this will be an ethical problem for the future.
