Bryan Johnson tells a naval story about a commander who refuses to change course, calling himself a lighthouse that cannot be moved. He uses it to argue sleep should work the same way: a fixed, non-negotiable schedule you don't sacrifice for other priorities.
A commander of a naval fleet is navigating and one of their shipmates wakes up the commander and says, come up. I need to look at this thing happening. And they find an oncoming object. The captain radios them and says, Change your course 30 degrees north. Not wanting to do that, he radios back. You change your course, you know, 30 degrees south. He invokes his authority. I'm a blank star of this naval fleet. Comes back. The response I'm a lighthouse. We use stories of authority to justify changing sleep. We consider it to be something we can just push around. And when you shift your mindset to say sl sleep happens at a specific time, it changes your relationship with it, so you no longer push it around. Because our culture is we can always push sleep around to accommodate other objectives. It's the one that always gets the short end of the stick.
