A child born in South Korea in 2024 can expect to live 83.7 years — but only 65.5 of them in good health. The effort to close that 18.2-year gap is what we call longevity. soundbasis is a journal that asks, through three different lenses, whether those efforts stand on real evidence.
The word used to mean simply living a long time. Today it points to something more specific.
Not how old you get, but how long you can walk, remember, and run your own life.
Instead of fighting cancer, heart disease, and dementia one by one, it targets the process of aging that they all share.
If you can't say what you're measuring and how it connects to real health, it's closer to a lifestyle habit than to longevity.
The time it took South Korea to go from an aged to a super-aged society. Germany took 37 years; France took 39.
The hallmarks of aging described in the journal Cell grew from nine in 2013 to twelve in 2023. What can be taken apart can be targeted.
The amount one aging-research company launched with in 2022. Outside the lab, supplements, tests, and clinics are moving even faster.
Interventions backed by decades of evidence and ones with thin human data both carry the "longevity" label. Put the scientist's lines side by side and the difference shows.
The same topic leads to different conclusions depending on who's looking. Rather than hiding the disagreement behind a single score, soundbasis sets the three lines side by side.
Instead, we'll be honest about how far the evidence has come — and where expectation begins.
