 And in the U.S., I think we started a ban on leaded gasoline in the 70s or so, right, Peter? Yes, we did. But there are still some uses here and there for leaded gasoline. In the United States, still perfectly legal. One is general aviation. Small propeller-driven planes can use leaded fuel. And some lawn equipment can also use leaded fuel. But for the most part, it's been gone. And the beneficial health impacts show very strongly here.
