Nobody knows the exact answer to this question but the transchrono community can probably get the closest. Transchrono individuals already experience sensations that are close to what people may feel in a truly infinite world. The general population would take time – possibly generations – to properly grow accustomed to the realities of immortality.
Indeed this reality may be far off. But not unimaginably far off. Reasonable scientists who are experts in the area of aging are optimistic that a major breakthrough can take place in the next 25 years. This means that most people alive today can reasonably expect to live to beyond societally-defined 120 years.
How far are we from immortality?
Scientists are conflicted on this question, but it could be as little as 25 years away, according to experts on the subject
There are several routes and major obstacles that need to be overcome if man is to become immortal. First of all, we must conquer physical aging. That is, modern medicine must invent ways to halt the natural wear and tear of cell splitting and other forms of deterioration on the body’s organs. Second, modern medicine must find ways to cure common deadly diseases or else statistically everyone will get one or more of them in an infinite lifetime. Finally, we as the human race need to put an end to man-made causes of death like war, famine, and over-population.
But after all this, assuming we get to this point, what is the mental age of your average person? How do we define someone’s age? What distinction is there between someone who has lived 145 years and 170 years? There is of course minimal difference. One solution which we have proposed in another article “Eras, not Ages”, is that rather than age, a person should be defined by the Era they are in (see more there for details). Another solution would be to completely abolish the concept of age altogether and make it illegal to talk about it.
How will we measure “age”?
One solution, formalized in a future article, is to use “Eras” rather than Ages. Read more about it here
In the meantime, we can learn from the future about how to conduct ourselves today. Yes, most lessons for today are from experiences in the past, but appropriately, transchrono lessons can be drawn from any point on the Earthly timeline.
