A great deal of longevity content is priced for somebody else. Full-body imaging, continuous monitoring, a supplement shelf that costs more per month than most households spend on food. It is worth saying plainly: almost none of that is where the returns are.
The interventions with the strongest evidence behind them are, awkwardly for the industry built on top of them, the cheapest ones. Here is the order we would actually spend in.
Free, and the largest effect
- Sleep — protecting the window, and getting a real diagnosis if it is broken
- Walking, daily, at a pace that makes conversation slightly harder
- Strength work you can do with body weight and one heavy object
- Not smoking, and being honest about alcohol
- Keeping people in your life on purpose rather than by accident
If nothing on that list is fully in place, spending money further down this page is buying a smaller effect at a higher price.
Cheap, and worth it early
- Blood pressure, checked properly and regularly
- A basic metabolic and lipid panel, so decisions are made on numbers
- Dental care, which is cardiovascular care more often than people expect
- Vitamin D and iron where indicated, not as a default
Worth paying for once you have the basics
- A movement screen before you load a body with old injuries in it
- A dietitian, once, to build something that fits how you actually shop
- A sleep study, if the history points at apnoea
- Coordination, if you are managing more than one thing at a time
Spend from the top of the list down. Almost nobody does, and it is the single most expensive mistake in the field.
This is also why Root exists and costs nothing. The information and the community around it are the part of this service with the widest reach, and putting them behind a fee would have meant the people with the most to gain never saw them.
