Interesting.
When it starts happening, parents will never see their kids really grow up.
Some of us believe we’re seeing that now.
I’ve always thought one way to accomplish life extension through artificial influence might be to gradually raise the age at which people are permitted to have children.
Do it gradually; increase the minimum by one year for every two that passes.
It would be a slow progression. But for those concerned about ostensible “overpopulation”, this would begin putting the brakes on in relatively short order.
Of course, this could only happen in a land that controlled its borders and its immigration. So, obviously it’s only a mental exercise at the moment.
When you think about how humanity got a jump in longevity on its related species, this would seem to be a part of the formula. It could work again.
Another thought is to study already long-lived species, and compare their genomes to closely similar but much shorter-lived species, to find the telomere-like markers that define and produce the marked differences.
