What is extremely hard when trying to understand our bodies, is that everything happens at the same time.
At the same time we register our feelings, all other things in our body also happen simultaneously.
For your body, this is a hard concept to explain. This is where consciousness comes into play.

It works like this: first we register things one by one. “Ah, a feeling.” Over time, the complexity and speed increase, and your body starts to accelerate the explanation.

Consciousness has a lot of levels, dimensions, horizontals, verticals, religious sides, etc. It’s extremely tough in practice. Every time you think you know, you don’t.
