I learned that the human body has essentially two types of nervous system - one for sensing the outside and one for sensing what’s going on inside. Our sense of consciousness is, oversimplified, the integration of the two.

The system responsible for sensing how life is going within our bodies — the system that tells us we’re thirsty, hungry, feeling nauseated, in pain — has tons of redundancy built into it. That system isn’t myelinated, it doesn’t have a protective sheath around it, and it integrates directly with our brain. It’s highly inefficient.

You could lose your sense of sight and still survive and thrive. If you lose your ability to sense your body’s internal happenings, you could not. (again, oversimplified).

Something so important must have tons of redundancy. Something so important can’t be easy to break.

Systems that are inefficient aren’t easy to break.

So here’s a question… how inefficient are the most important systems in your life?
