Early Risers
The circadian case for rising early — cortisol timing, morning light, and why a regular sleep schedule outpredicts sheer sleep duration. Plus the quiet edge of living on the equator.
The Fable Tax Never Left
Anthropic said Fable 5 was included in my Max plan starting July 20th. My terminal spent every session since sending me to a credits page instead. The bug behind it, the pattern behind that bug, and why Opus 4.8 is my default again.
No Day Off
While Colombia took Independence Day off, we didn't: the kids on the MMA mats, me under the bar for leg day, all of us in the pool afterward. Not grind — culture. Why a holiday is the truest test of whether your habits are real.
Once a Biohacker, Always a Biohacker
Genetics is the hand you're dealt. Thirty years of showing up is how you play it. Why the discipline I started at sixteen became the one thing I'd never trade — and never quit.
The City of Eternal Spring
Some places make healthy living feel like another job. Medellín quietly removes half the excuses, opens the windows, and sends you outside — and the climate turns out to be the best biohack I never bought.
Kimi K3: The End of Cheap Chinese AI
China's answer to Claude and Codex is a 2.8-trillion-parameter open model that topped the coding leaderboard two days after launch — and priced itself like the frontier it just joined. Here's whether Kimi K3 belongs in your stack.
The Fable Tax Moved Inside the Plan
The surcharge is gone, but the economics didn't budge. Anthropic didn't make Claude Fable 5 free — it found a subscription-shaped way to charge twice.
The Most Biohacked Thing at Ritwal Wasn't the Food
If your idea of optimization can't survive lobster, a tomahawk, and a long dinner with people you love, the protocol is the problem.
Three Months In
Ninety days on a full hormone-and-peptide protocol. The vials are running dry, a blood panel is two weeks out, and after three years the Cuban cigars are done as of today. Round one was the learning curve — here's the scorecard before the real plan begins.
The Cost Control Plane
Your agents run at max reasoning, in YOLO mode, around the clock — and the bill scales with ambition, not headcount. The fix isn't a cheaper model. It's a control plane: see every dollar, send judgment to the frontier and volume to the floor, cache hard, and bound every loop.
678 Korean BBQ
One normal day in a biohacking family: the kids burn energy at football, then refuel on grilled protein and a table full of fermented vegetables — and I get a clean run at my own inputs. Here's why Korean BBQ is quietly one of the best meals a biohacker can order.
Smooth Skin & the Colombian-Arab Chef
Two updates: a Colombian-Arab chef teaching the kids to cook — with the real science on why the Levantine pantry is one of the healthiest on earth — and a follow-up to the oily-skin post. The skin turned smooth, and the honest reason is mostly metabolic, not the peptides.
