Americans are dumber because of leaded gas study shows.
From 1951 to 1980, nearly every American child had unhealthy lead levels.

We’re covering the infuriating story of leaded fuel. There are three main topics we need to cover:
1. We knew it was dangerous from the very beginning, yet used it for an entire century. We started off with ethanol, then decided to poisoned ourselves for a hundred years, then came back to using ethanol.
2. We’re STILL using it today. If you're near a local airport, you're likely breathing air with leaded fuel exhaust.
3. A new study indicates we’re dumber because of it. Like, all of us. Especially if you were born between 1951 and 1980 three decades of incredible amounts of lead in children's bloodstreams.
