We're also very good at not thinking about certain things, though. And I doubt anybody would make a system of immortality that didn't have an escape hatch.

Alpha Centauri is prescient as ever on this subject:

>I plan to live forever, of course, but barring that I'd settle for a couple thousand years. Even five hundred would be pretty nice.

Of course, we would surely need to expand to other planets before we got anywhere near a 500-year lifespan. We can't manage this planet's resources properly even with a 70-year one.

Fortunately this technology does nothing of the kind. Crashes, choking, and shower falls just to name a few enduring killers will continue to cull our numbers. Even with aging itself there are many factors involved so making major progress does not mean eliminating aging, just greatly reducing the impacts.

it depends. who gets to live forever and what is the cost of living forever?

i can totally see this being unrealistic/unpractical for the majority of people which bring in another can of worms
