No matter your age, there's always something so satisfying about learning new, interesting fun facts. Even better when you get to share those tidbits in conversation. Lull, avoided. People, delighted. it's a win-win.

Trivia exists for every interest, too. Maybe you’re a wordsmith and will be fascinated to learn that a fear of long words is called Hippopotomonstrosesquippedaliophobia — or that the longest English word is way longer than that one. Think: 189,819 letters long.

Then there are fun facts that will remind you just how different — and quirky — people are all around the world, doing things you wouldn’t even think to make up for movies. Like how a woman in the U.K. once called the police when her ice cream didn’t have enough sprinkles. Or that someone purchased a lock of Neil Armstrong’s hair for $3,000 in 2004. Perhaps you want something a little more … useful? Well, while Rhode Island is the smallest state in the U.S., Vatican City is the smallest country in the world.

It’s always a good time to learn something new. In fact (no pun intended), learning fun and interesting facts and trivia knowledge can actually have a positive effect on your ability to remember new information.

Knowing a handful of offbeat and entertaining facts is also a great way to connect with others. Whether you're trying to come up with an icebreaker at work or impressing your in-laws with your world history wisdom, there's an interesting fact for nearly every situation.
