It's official: Being grossed out is actually good for you, a new report says. Experts say the emotion of disgust exists to keep us away from gross, potentially harmful stuff.
Just as fear protects us from a lion that would eat us, "disgust is quite similar. It keeps us away from tiny little animals that would eat us up from the inside," said Valerie Curtis of the London School of Hygiene and Tropical Medicine, the lead author of a paper published today in the Philosophical Transactions of the Royal Society. "We evolved to stay away from poo, from bodily fluids, from mucous, from foods that have gone off, from worms in the garden."
You're welcome.
