In my mid 40s, basically perfect health (people often think Iām early 30s). Would still love to be back in my biological 20s again and would def prefer age reversal back to a biological fit 20s, 30s or 40s state vs a healthy, but still decline in function 60s, 90s or 100+ās.
Whether biological vitality of a 20 year old will be fun for an extra 100, 500 or a 1000 years or shorter or massively longer feels tough to say today.
The world could become amazingly good and exciting compared to anything human civilization has seen over be the next decades or centuries - or it could go in the opposite direction or even be game over for humanity.
But I definitely see many decades of fascinating and exciting things ahead that I want to see, do, contribute to and be part of. Iād image Iād feel the same in 150 years - if eg healthy, biologically young and wise and in harmony from a wealth of experiences that come with chronological time and e.g. on way to vacation on Mount Olympus on Mars with my great, great grandkids and generations in between for a favorite skip trip. And so on and so forth.
Imagine Napoleon or Cleopatra thinking about what our world in 2024 would look like - in the same way we almost certainly fail in imagining what our civilization, solar system and technology will look like in 50 and 100 years from now, let along 500 or 1000 years from now (and perhaps even just in 20 years).
So while I feel indefinite life seems like something desirable, Iām not sure that means infinite is/will be.
Declining function, disease and unwanted death definitely seem like some of the most terrible things that still plague human kind.
And think about scenarios that go well over the next decades to century or so (friendly, collaborative AGI, cracking fusion, developing advanced molecular nanotechnology) - in those cases we will likely enhance our individual cognition, our bodies and our ability to experiments and process our world in truly unfathomable ways.
