Last week in longevity science, read for you by Monday.
Every week the field produces about thirty hours of podcasts, a handful of papers worth knowing about, and more essays than anyone can read. Last Week: Longevity goes through it and gives you two paragraphs on each item that mattered, so you can decide what deserves your full attention.
Free. First issue at the end of 2026. One confirmation email now, then nothing until the first issue. Unsubscribe in one click.
One email, in three parts.
- 01The highlights.Two or three items the editor thinks mattered most that week, with a few lines on why.
- 02The full week, sorted.Everything else that passed our read, grouped as Podcasts, Research and Articles. Each gets two short paragraphs: who spoke or wrote, what the central topic was, one or two highlights, and whether it is worth your hour.
- 03The links.Every item links to the original episode, paper or article, and to a slightly deeper summary on our site. We send you to the source, never away from it.
Two paragraphs and a link.
What the Zone 2 evidence can and can’t say
[Guest], a cardiologist who runs an exercise physiology lab, spends most of the conversation separating what is measured from what is inferred. The association between aerobic fitness and later health is well documented in large cohorts; the specific prescription of long, easy sessions is a reasonable reading of mechanism and smaller trials, not a settled finding, and [guest] says so plainly.
The second half is the useful part for most listeners: how to tell a trend from noise in your own numbers, why a single fitness test is a poor baseline, and what a good one looks like. Listen if you train by heart rate and want to know how much of the Zone 2 advice is evidence and how much is habit. Skip it if you have heard [guest] on this before; little is new.

Machines find, a person decides.
A pipeline watches the feeds, fetches transcripts and papers, and drafts a structured record of who claimed what, with what evidence, and how firmly. Then a person reads it. Nothing is sent that has not been read and approved by the editor, and the pipeline works under strict rules: extract, don’t infer; when in doubt, leave it out; attribute a claim to the person who made it, not the host who summarized it; keep “well established” and “early hints” apart.
We publish two paragraphs and a link, never a transcript and never a summary long enough to replace the original. If you can read our item and decide whether you want the real thing, we have done the job. If you can read it and decide you don’t need the real thing, we have overstepped, and we would like to hear about it.
Edited by Csanad Novak, founder of Vitality Tracker, who was listening to most of this long before there was a newsletter.
Three things it will never be.
It is a reading guide to other people’s work. Nothing in it is advice about your health, and we don’t tell you what to take or do.
The item tells you what was discussed and by whom. The nuance lives in the original, and we link to it every time.
It is free, and your address is used for this and nothing else. If an issue ever carries a sponsor, it will say so at the top.
Calibrated before it is sent.
We are building the pipeline now and will run it quietly for several weeks before anything is sent, so the first issue arrives already calibrated. Subscribe today and you will receive one email asking you to confirm, then nothing until the first issue at the end of 2026. No teasers, no countdown.
Also in the Knowledge Base.
Everything the newsletter covers also goes into a searchable Knowledge Base inside Vitality Tracker: by topic, by expert, by claim, with a view of where sources agree and where they don’t. It is part of every plan, including the free one.
In your words.
Once a week, on Mondays. Nothing else from this list, ever.
Yes. If an issue ever carries a sponsor, it is labeled at the top, and your address is never shared or sold.
No. The newsletter and the summaries on our site are public.
The finding, transcribing and first drafts are done by our pipeline. Every item is then read, corrected and approved by a person before it goes out, and every claim is attributed to the person who made it and linked to the source.
No. It tells you what was said, by whom, on what evidence, and whether it is worth your time. Decisions about your health belong with you and your doctor.
Yes. Every item has a page on our site, published the same Monday.
The major longevity podcasts, the research journals, and the newsletters the field reads. The full list is published with the first issue and grows with reader requests.
