Although cougar attacks on people are still (thankfully) pretty rare, there’s a place in the world where big cats kill and eat people pretty much every other week. In the Sundarban Islands in India, about two dozen people get killed and eaten by tigers every year. Over the past few decades the local villagers have tried lots of tricks to dissuade tigers from attacking them, but probably the most effective has been this: they wear masks on the backs of their heads. Tigers, like most cats, always prefer to attack their prey from behind. Villagers who wear the masks when out and about in the jungle get attacked way less often than those who don’t.
