Funny thing, a lot of people involved in the secret projects are older than they appear. This could happen through two ways. An individual is brought into operation in the dream state and they regularly experience one continuous day eventually living two completely separate lives simultaneously. Or they are brought into a longer term scenario and undergo age-regression/reversal and “reset” the biological clock.
This sounds outlandish but is one of the many entirely unique perspectives that the advanced technology enables.
Everyone talks about the new mode of human existence, it could merely reflect the changes that occur on a civilization wide level when the energy use becomes so advanced that the current tech is considered outdated.
