 Now, you may imagine that antibiotic resistance is a threat that's looming, but it's still over the horizon. But from my perspective, working in the hospital, it has very much already arrived. And it's getting worse. And it all stems from overuse. Putting antibiotics in places they're not needed. But my conversation with Charles left me wondering something. Why did we used to give so many antibiotics to chickens which didn't have infections? And why are lots of countries still doing this?
