The boring basics
The consensus core of aging well — movement, sleep, food pattern, not smoking, social ties — and why everything exotic should be benchmarked against it.
The list
Strip away the frontier science and the marketing, and the factors with broad, boring, decades-deep support for aging well fit on an index card:
- Regular movement, including strength work (exercise, sarcopenia)
- Adequate sleep, defended rather than surrendered (sleep and aging)
- A mostly-plants, mostly-unprocessed food pattern — the shape of every mainstream dietary guideline, whatever name it trades under
- Not smoking, the single largest self-inflicted variable on the card
- Alcohol modest or absent
- Social connection and purpose — consistently associated with better late-life outcomes, and the item most often left off lists because it can’t be sold in capsule form
Why the list is credible
Because everything on it is supported from multiple independent directions — epidemiology, trials where feasible, mechanism, and the absence of any serious school of thought arguing the opposite. No single study, however famous, carries the list; that’s precisely its strength. Compare the typical longevity headline, which rests on one mouse study and a press release.
The benchmark rule
The card’s practical use is as a measuring stick. Before adopting anything exotic, two questions:
- Am I already doing the boring basics? If not, the exotic thing is a distraction — nothing on the frontier approaches the effect of covering the card.
- Is the new thing’s evidence within shouting distance of the card’s? It almost never is. That doesn’t make frontier research worthless — it makes it research, which is a different thing from guidance.
The uncomfortable honesty
The basics are unmonetisable, which is exactly why the surrounding industry talks about everything else. A reference site has the opposite incentive: this entry is, deliberately, the least novel and most important page in the index.
