How might genetics of Hydra and jellyfish steer healthspan research forward?

[John14]

I was reading about how some researchers are now studying the genetics of extreme longevity in simple organisms like hydra and jellyfish, not for human life extension, but to understand cellular repair mechanisms that could prevent age-related diseases. It seems like a shift from chasing longer lifespans to targeting longer healthspans. For anyone following the genetics research, do you think this refocusing on model organisms for disease prevention is where the most practical near-term breakthroughs will happen?
