In plain English
Longevity basics, explained simply
The basics are less flashy, but often have stronger human evidence than experimental interventions.
Start with these 3 questions
Is this intervention supported by human outcome data?
What is the minimum effective habit?
How does recovery change risk?
What should you do with this information?
- Use it to ask better questions.
- Look for human evidence, not only exciting mechanisms or popularity.
- Do not judge a claim by influencer attention or marketing language.

Question
What actually works in longevity before experimental interventions?
Before experimental interventions, the best-supported longevity work is usually cardiometabolic risk management, exercise, strength, sleep, nutrition...

Question
Zone 2 training and longevity
Zone 2 training can be a useful way to build aerobic capacity, but the longevity target is broader cardiorespiratory fitness and consistency, not wor...

The evidence ladder
We ask a simple question first: how close is this claim to proof in real people?
- 1
Proven enough for standard use
Human evidence and accepted medical use for the specific purpose.
- 2
Promising but not settled
Some human data or strong early evidence, with important questions still open.
- 3
Mostly animal or lab evidence
Interesting science, but not proof it works in people.
- 4
Theory, hype or anecdotes
People talk about it, but reliable evidence is weak.
- 5
Regulatory or safety warning
The main story is approval status, legality, quality or risk.

FAQs
Are basics less interesting because they are not new?
No. Many boring interventions have stronger human evidence than frontier claims.
