Let's start with a phrase you've said a hundred times without thinking about it: "mad as a hatter."
It isn't just a bit of whimsy from Alice in Wonderland. For centuries, hat-makers used mercury to turn animal fur into felt — and breathing its fumes, day after day, in poorly-ventilated workshops slowly poisoned them. The result was a syndrome doctors called erethism: tremors (the "hatter's shakes"), crippling anxiety and irritability, memory loss, personality change. An entire trade was, quite literally, being driven mad by a heavy metal. Mercury is a spectacular poison — it wrecks the kidneys and the nervous system — and we have known this for a very, very long time.
Which makes what I'm about to tell you all the more depressing. Because mercury didn't just disappear when the hat factories shut down. Today, it's in skin-lightening creams — and it's still poisoning people, right now, in 2026.
