Yeah, he was the guy that we first started reading about that was saying that a disproportionate amount of motorcycle victims, when he was doing his residency, the guy who he was working with, one of the surgeons, would test the motorcycle victims for toxoplasmosis. And he said a giant percentage of them have this cat parasite.

This cat parasite alters behavior. It makes you more reckless. It makes you more prone to erratic mood swings. It makes you more aggressive.

A disproportionate amount of successful soccer teams have high levels of toxoplasmosis.

So what it does is it rewires a sexual reward system of rodents. And like mice and rats get turned on by the smell of cat piss. So they go to seek out cat puss with like a boner, like literally. And they lose all their fear of cats so that the cats devour them. And so when the cats devour them, then that parasite is now inside the cat's gut, which is where it reproduces.

But there was one point where in France, it was like 50% of the people had toxo.

And that parasite, toxoplasmosis, is it affects humans. It affects behavior. It makes you more impulsive, more aggressive.
