Decode Your Wellbeing: The Full Guide to the Longevity Boom, in Eight Parts
Age reversal, biological-age tests, senolytics, and the habits that actually hold up. A clear-eyed guide to the longevity boom, one claim at a time.

The longevity boom runs science, hype, and marketing through the same microphone. This guide is an attempt to separate them. Over eight parts we take the biggest longevity claims of the year one at a time, ask what the evidence actually shows, and mark clearly where the research stops and the sales pitch begins.
Each part answers a single question in plain language, from what a biological age test really measures to whether age reversal in human trials means what it sounds like. Read straight through, or jump to the claim you are trying to make sense of.
The short version
- Age reversal did reach human trials this year. What that sentence means is narrower, and more careful, than the headlines suggest.
- The habits with real evidence make a short list, shorter than the supplement aisle implies. Most of the longevity market sells around the edges of that list.
- The most useful skill here is reading the science without getting fooled. One part is devoted entirely to telling which voice, research or marketing, is talking.
The series, claim by claim
Age reversal, in human trials. Age reversal left the petri dish and entered human trials this year. What that sentence does, and does not, actually mean.
The six habits that hold up. Six habits with real evidence behind them, and the reason the list is shorter than the supplement aisle would suggest.
What a biological age test tells you. You spat in a tube and a number came back. What the test is really measuring, and how much to trust it.
Mitochondria, honestly. The organelle that turned into a wellness brand. What mitochondria actually do, and what you can honestly do about them.
The zombie-cell theory. Senescent cells sound like a villain with a clean solution. Where that tidy story holds up, and where it breaks down.
Protein and recovery after 40. Recovery gets slower after forty, and the internet blames protein. What the research supports, and where it stops.
How to not get fooled. The field runs science, hype, and marketing through one microphone. A practical way to tell which one is talking.
What it all adds up to. The wrap. A week inside the longevity boom, and a strategy for living in it without becoming either a mark or a cynic.
