Why the f**k does swearing feel so f**king good? There’s a reason a lot of us pepper our speech with profanity — and it has a lot to do with how our brains are wired, according to The Economist. Swear words activate a different region of the brain than that used in regular speech — an area near the center that’s activated when we cry or scream, suggesting that swearing is closely connected to expressing “our most basic emotions.” The object of our swearing is also an important factor to look into, and varies across cultures and languages based on what people perceive as fair game or a red line (watch, runtime: 3:03).
