Life extension research does this by focusing on "healthspan" - that is, the amount of time you spend living in full health. The idea isn't to let you live 200+ years as 80-year-old person. The idea is to let you live up to 80 as if you're 30-40 - that is, to extend the time you're fully able to function and enjoy life - and push it out from there, keeping the tail-end small and extending the total lifespan. This happens to both offer huge potential healthcare savings, and meshes nicely with the idea that everything happening to your health past ~40 is part of the disease of aging.
