My previous book, Gut Check, I introduced people to a little one cell organism called toxoplasmosis. which is a single cell parasite that has, like many parasites, has two life cycles. And many parasites have to spend some time in an intermediate host to get to their final place they really want to get to. And toxoplasmosis wants to get into a cat, and that's where it wants to go.

And many parasites have to spend some time in an intermediate host to get to their final place they really want to get to. And toxoplasmosis wants to get into a cat, and that's where it wants to go.

And its intermediate host is strangely selected to be a mouse or a rat. Now that's a really, you would think, a dumb idea because mice and rats are deathly afraid of cats. If they smell cat urine, they run the other direction. But toxoplasmosis gets into a rat or a mouse through contaminated water that a cat has pooped in. And

It basically goes to the brain and literally rewires the brain, primarily using dopamine receptors. And it makes the smell of cat urine sexually stimulating to the rat. And it also makes the sight of a cat incredibly exciting. And the rat literally runs to danger and gets eaten. Now, what's so interesting about that

is we know that great apes particularly chimps can be infected with toxoplasmosis and why because believe it or not tigers big cats chimps are one of the favorite foods and these animals become emboldened around tigers

great studies out of yellowstone park showing that most wolf pack leaders are infected with toxoplasmosis because believe it or not the predator of a wolf is a cougar a mountain lion and they become more bold take more risks and that's actually how they become leaders What's really scary is that humans can be infected with toxoplasmosis and people who are infected with toxoplasmosis.

For instance, the vast majority of motorcycle riders in fatal accidents are infected with toxoplasmosis. And at one point, the U.S. military was very interested in infecting troops with toxoplasmosis so that they would run towards danger.

So the reason I brought that up in that book and the reason I talk about more of this in this book is the power of a single cell organism to completely rework our thought process for that organism's benefit. And in that case, it's a parasite. But the parallel, the organisms, if they're in balance within us, want to try and get the food that they need to take care of their apartment building.
