What people say
From LinkedIn
Well expressed. There is so much hype and claims of making castles in the air.
Prof. Dr. Suresh Rattan Emeritus biogerontologist · Aarhus University
Really good, common sense. I agree with everything you say. Wisdom isn’t the exclusive domain of the elderly.
Rob Scott, MD Chief Medical Officer, AbbVie (retired)
Inspiring to see the focus on doing the basics well. It’s amazing how much progress comes from consistency rather than quick fixes.
Dr Tamsin Lewis Longevity doctor · Founder, Wellgevity
Love how you make this clear. People often chase the next shiny thing instead of mastering the basics.

01
Why most "longevity" is noise.

The five pillars that move the needle vs. the supplement-industrial complex.

02
Biomarkers worth tracking.

What ApoB, VO₂max, and Lp(a) actually predict — and why most dashboards make you worse.

03
Prevention vs. prescription.

Why the system rewards late-stage care — and how diagnostics-first clinics shift the model.

04
Inside an N=1 experiment.

Lessons from Project Peakspan — what 87 biomarkers and 14 interventions actually moved.

The ground truth

Boring beats biohack.

Most of the longevity gain comes from a handful of pillars. Supplements, peptides, and €400 patches fight over what's left.

Read the essay →
01
Sleep · 7–8 hours, consistent.

The only intervention every meta-analysis agrees on. A single bad night tanks your health. Free. Non-negotiable.

02
Zone 2 + HIIT · at least two times per week.

Zone 2 builds mitochondrial density. HIIT drives VO₂max. Both predict health better than most blood markers. Do one, get half the benefit.

03
Strength · twice a week, hard.

Strength and muscle mass predict all-cause mortality better than most blood markers. Lift heavy things. Then go home.

04
Nutrition · whole foods, fiber, protein at every meal.

Ultra-processed calories drive almost every metabolic disease we track. Fix the inputs and most downstream labs correct themselves. 1.6 g/kg protein, healthy fats, fruits & veggies, enough fiber.

05
Relationships · the one most men fail.

Loneliness rivals smoking as a mortality risk. The supplement stack won't save you from a lonely Sunday.

+ annual diagnostics, sun, and the occasional frontier intervention where evidence permits.

PEAKSPAN
The protocol · the open ledger

Project Peakspan.

An open N=1 experiment. Every diagnostic run at YEARS, every intervention dated, every result posted — good or null.

Blueprint shares a protocol. Slowager shares a journey. Peakspan shares the raw ledger — biomarkers, interventions, and honest answers about what actually moved. Updated quarterly. Free.
