Twenty-One Markers and an ECG
Seven in the morning, fasted, at home. Everything the clinic ordered plus all five things I asked for on top — including the one test that settles the iron question. Full list, and why each one is on it.

Meta Ray-Ban Display: $799, One Eye, and a Wristband That Reads Your Nerves
Every review said great hardware, no apps, wait. Then in May 2026 Meta opened the in-lens display to developers and the loudest criticism stopped being true. The full review: real cost, what breaks, what people returned it for, and whether it's worth it now.

These Are the Final Results. Nooot.
Testosterone up 56% measured at its floor. Estradiol up 215%. And six iron markers leaning the same way, which is the finding nobody would have flagged. Then, hours after the PDF landed, a message that made the word final premature.

MONSTER 2.0 — The Blueprint
Six days, built from an AI scan of every machine on my gym floor. Ten kilos of fat out, no muscle back. Every term defined, every set and rep, and an illustration of the start and finish of every exercise.

The Sword Goes Back in the Sheath
Pushing through when you're tired is half a rule. The other half is stopping deliberately, at a moment you chose. A weekend in the Eje Cafetero, a clinic that took ownership when it didn't have to, a product going live, and the only test of a system that counts.

Even If You Are Tired, Keep Moving Forward
I was tired, I'd napped, it was late, and I had already talked myself out of the gym using entirely correct principles. Then my son hugged me and said seven words, and the argument ended. On giri, why obligation beats motivation, and the honest cost of training at 22:00.

The Numbers Came Back
Triglycerides down 41%. VLDL down 43%. Non-HDL down 18%. SHBG up 54%. Six kilos gone. Liver spotless in both panels. Arteries reading up to seven years younger than I am. Ninety-four days of protocol, measured against a baseline drawn before I started — and testosterone is still to come.

Krv Nije Voda — Blood Is Not Water
There's a Serbian saying: krv nije voda. Blood is not water. At home it means your bloodline isn't negotiable — that the people you come from, and the people who come after you, are the one thing that never gets diluted. We're building something. More soon.

Five Tubes of Blood and a 688-Page Manual
This morning five tubes came out of my arm, closing ninety days on protocol. In six weeks Andrew Huberman publishes 688 pages of protocols. Both are called protocols — but only one of them knows anything about me. His science, his critics, his book, and what a blood panel does that a manual can't.

The Iceman Sent a Plumber
I bought the Wim Hof Fundamentals course and never opened it. Then my water heater died, put the whole house through three days of involuntary cold exposure, and one of my kids refused to stop. What the evidence actually supports, what it definitely doesn't, and the part that has killed people.

Envigado
You catch a good wave, you keep riding it. After years in Poblado the house is full — five or six people every day, cats, dogs, a family growing in about five directions at once. So I spent a couple of quiet months buying a house in Envigado.

What a Day!
A framed map of the stars over Medellín, a HIPAA milestone with six people across three countries, a blood draw, two brothers booking flights, a deal I can't talk about, and two extremely unhappy cats. All in one day. This is what I call building.
