This is a classic example of one of those studies that while interesting and funny, makes me question whether the time and effort could have been put into something more useful. Be that as it may, it turns out per studies conducted at the University of Michigan and the University of Southern California, the smell of fish can instantly turn you into a better problem solver. This all comes from a story at Munchies.Vice.com , but here's the gist. It's been known for a long time that fish is good for you, and in particular, past studies have shown fish is good for the brain. Well, this new study suggests that just the smell of fish has instant benefits. Per the article, while it's been proven that the nose acts as an early warning system against questionable-smelling food (and people, for that matter), the new research shows that it may also be able to alert us to suspicious ideas and concepts. Here's the short version of how the studies were conducted.
