The Manifesto

Most people end up overwhelmed —
and unsure who to trust.

01 / Clarity

Signal over noise

Health content optimizes for clicks. We optimize for decisions you can actually make. Fewer claims, more context, honest uncertainty.

02 / Pressure

Test every claim

Researchers, founders, clinicians, skeptics, innovators — and we pressure-test their ideas. Some viewpoints align, some clash. That is the point.

03 / Prevention

Before, not after

Most systems wait until something breaks. Longevity, performance and prevention start decades earlier. We make that case, episode by episode.

04 / Humility

Science & common sense

When evidence is thin, we say so. When something works, we say so. Trends die fast; fundamentals compound. We stay with the fundamentals.

✦
Every side gets a seat.We talk to people we disagree with. Real conversations change minds — theirs and ours.
✦
Incentives over intentions.Good intentions fail when incentives are misaligned. We follow the money and the defaults.
✦
Healthspan over lifespan.Years are cheap. Functional, independent, clear-headed years are everything.
✦
Skeptical, not cynical.Hype is a tax on attention. Dismissing every new idea is its own kind of lazy.

The Hosts

Two different angles,
one shared obsession.

Niko and Miguel met during their Master's at NOVA SBE. Late-night debates about health, medicine and broken incentives turned into a shared frustration with the system — and, eventually, this podcast.
