Longevity doesn’t “scale” when you add more tests, gadgets, or luxury. It scales when prevention becomes a repeatable program that fits real life: clear standards, conservative diagnostics, and follow-through that survives your normal calendar.

The longevity market is upside down: people are buying drips, stacks, and “frontier” tools while the basics are still unstable. This is a buyer’s framework for sequencing - so you stop paying for the top layer before the foundation exists.
