Swords, cannibalism, poison: inside the world of killer microbes

One idea people haven't thought about, and I think Ben kind of brought that up nicely, is every other cell is a pocket of food, except it is amazingly encased in a way that no one else can get it, right?

So if you ask microbiologists, I think you'll create... They'll always fight with each other because there's a school of thought which says, oh, everyone likes everyone.

So essentially, I think another sort of arena, as you said, is inside us.

So there's a lot of...

competition that's happening in my gut right now right because i just had breakfast so maybe my microbiome is happy it's getting food but if i had an extremely fiber heavy breakfast so no simple sugars no corn syrup etc bacteria have to make an effort to digest that right that those are these huge blocks of carbohydrates that's not like that's not easy for bacteria to degrade right inside me there's a lot of bacteria that cannot do this

There's some bacteria that can do this, right?

So the ones that can't do that, so, you know, we call them scavengers or exploiters, essentially have to depend on someone else, the degraders, to do this.

And if you don't want to do this, an easier way is, well, I use my weapon.

I wait for the degraders to do this.

I then come and kill you and then eat you, right?

But I mean, the degraders might seem to be, you know, things are stacked against them, but no, they have an important card in this, right?

They are the ones that can break down the food.
