UberFacts says it shares "the most unimportant things you'll never need to know" and I have to admit, that's a pretty accurate description of its content. Launched in 2009, the Internet project provides people with random facts on all kinds of topics.

From the number of janitors in the US with PhDs to the genius way Swedes protested their government classifying homosexuality as an illness, these titbits of information will make you an expert on trivia in no time. So grab yourself some broccoli (random fact: the vegetable is rich in vitamin K, and a few studies in older adults have linked a higher vitamin K intake to better memory), continue scrolling, and upvote your favorite entries!

As it turns out, there are some biological reasons behind people's desire to "store" trivia in their brain and the rush of excitement they feel when they get the chance to use it. According to psychologist John Kounios Ph.D., it's a lot like playing roulette, too.

"You get a rush or a neuroreward signal or a dopamine burst from winning," the professor of psychology and director of the doctoral program in applied cognitive and brain sciences at Drexel University in Pennsylvania, told Healthline. "I think whenever you're challenged with a trivia question and you happen to know it, you get a rush. It's sort of like gambling."

He said the benefits can also be similar to those of playing video games. However, unlike gambling and video games, trivia is generally not a potentially dangerous habit, Kounios said.

"I don't think there are any pitfalls. Like anything else that's fun, it takes up time."

Moreover, retaining information about things we're interested in can be like an exercise for the frontal cortex as the brain ages.

"That's the first thing to go with injury or with age if we don't use it," Deborah Stokes, Ph.D., L.P.C., B.C.N., a psychologist in Virginia who focuses on neurotherapy, said.

So there you have it, folks. Browsing trivia isn't a waste of time. It's a mental workout!
