Last month, I ran a marathon.

At km 30, I was so hungry I could barely run.

Two energy gels barely helped. My body wanted only hot food. It was raining, my emotions were loud, and a voice told me to let go of the numbers.

So I stopped at a stall and ate a bowl of beef noodles.

It sounds funny now. But it took more courage than any training run I have done.

I wrote about the marathon: why I would not recommend it to most people for long-term health, why I ran it anyway, and what spending 80% of my running in Zone 2 taught me about listening to my own body.

And yes, the beef noodles were probably the most important part.

Most of us think of AI as a way to get more done. I built mine to protect the conditions for thinking.

Many things happen in the brain at once. But I can only do one thing at a time: one word, one task. So I built a second nervous system to work alongside me, connecting my health, knowledge, decisions and daily tasks.

15 AI agents. Five parts. One question: who is the conductor?
