Does acetaminophen reduce empathy?
"Researchers from The Ohio State University have found evidence that acetaminophen not only dulls physical pain, it also reduces our ability to predict pain in others and empathize."
"If the results are replicated, they would be highly relevant to the real world. After all, it would mean that one quarter of the population would be regularly taking a drug that reduces empathy."
So now, besides how it harms the liver, it also has brain effects! (I've always been wary of the stuff, and how strongly it has been pushed on us.)
