It's ripe for inflammation because of the CO2 and because of the ammonia and the waste products.

And if that inflammation occurs, you get buildup of tissue, in particular, adipose tissue can really thicken, skin can thicken, and it starts becoming chronically inflamed.

And this is something that, believe it or not, is fairly common.

It's common in people who are obese.

It's common in people that don't move enough.

We'll talk about why that's so in a moment.

The lymphatic system's just basic role for draining that fluid out of the interstitial space is something that all of us should really care about, healthy or unhealthy.

So even if you're not obese, you need to get your lymphatic system tuned up so that it's clearing that

It's clearing what we call lymph, which is kind of like a sticky fluid because it's got stuff other than water in there.

It's got all those waste products and it rarely has red blood cells in it, but it often can have a few white blood cells and it can have some other stuff in it.

And we need to clear that out.

So it's semi-viscous.

It's not super fluid.

It's not a gel.

It's kind of somewhere in between.

And we need to clear that out.

In fact, if we don't clear it out, our body very quickly goes into local or systemic inflammation.

And if we don't clear it out within the brain, we get what's called brain fog.

You get cognitive impairment.

And the brain fog that occurs from lack of lymphatic clearance from brain tissue comes on very quickly, even after one poor night's sleep, and it is very severe.
