And they're collecting information from your gut.

There are in your gut 500 million nerves, feeling and sensing.

by the microsecond.

And all that information that gets collected by 500 million nerves, by the way, I should add that 500 million is a ridiculous number.

So, I mean, I know that sounds like a lot.

I mean, it sounds ridiculous.

But just to compare this to your spinal cord, this is five times what you will find in your spinal cord.

That's right.

So yeah, so you have five times more nerves in your gut.

This is why we call it the enteric nervous system, or some people will call it the second brain.

I actually would challenge that.

I would call it the first brain.

Serious.

Okay, so here's why.

From an evolutionary perspective, for you and I to be here, it required us to evolve and mature our brain, right?

But the problem is that a tree can't grow until it puts down roots.

The roots must come before the tree grows up.

The brain cannot be strong without nutrients.

We developed our enteric nervous system before we developed our central nervous system, which is our brain.

So from an evolutionary perspective, this actually came first.
