Body Systems

This is a roadmap, not a finished guide. Nothing below is published yet, so the list at the bottom of this page is empty on purpose rather than broken. Sleep is the one being written first, because it sits upstream of most of the others.

I think of the body as a stack of interacting systems. Sleep changes cognition. Gut problems change mood. Environment changes baseline stress. Skin, hair, vision, oral health, and appearance all feed back into identity in ways people like to pretend are shallow.

The goal here is not optimization theater. The goal is to understand the system well enough to stop guessing.

Planned threads:

• Brain: attention, mood, memory, motivation, and reward.
• Sleep: recovery, timing, light, and routines that actually survive contact with real life.
• Gut: digestion, inflammation, appetite, and the gut-brain loop.
• Environment: air, light, noise, temperature, and the room as an input device.
• Body: strength, pain, energy, posture, and capacity.
• Skin, hair, oral health, vision, appearance: the visible edge of the system.
