Seriously though, what is the point? You're gonna have the same fomo with death in the future as you do now.
We've already found out how to reactivate those growth and healing mechanisms. Have children, then grand children, then great grandchildren, etc. Each generation gets its own activation
I'm sure my ancestors worried constantly about their next meal because starvation was a very real possibility, but luckily I don't think about starving even though it's technically still possible. I hope that in the future the same is true of disease and non-accidental death.
The point is having as much time as you want to do the things that interest you. Nobody should be forced to live when they don't want to, and nobody should be forced to die when they don't want to. Pretty simple really.
> We've already found out how … Have children
Come on now, we both know that a legacy isn't remotely the same as not dying.
On a more relatable scale, humans do grow in complexity, order, and capability in their early years, until eventually decay turns the tide toward the end of our natural lifespans. It would be rather odd if it's physically impossible to re-activate those growth and healing mechanisms—much more likely that we just haven't figured out how yet.
[Edit: I'm amazed at the posts saying it's not worth trying to live longer because you'll never outlast A STAR. It's not a competition people!]
