Why Do We Say ‘Time Flies’ When We’re Having Fun?

"Time flies when we're having fun because our brain is too busy enjoying things to notice how fast they go."

Imagine you’re on a super-fast roller coaster. You’re laughing so hard, eating cotton candy, and shouting with your friends. Your brain is like a kid in a candy store, it’s excited and busy, so it doesn’t pay much attention to the clock.

But when you're doing something boring, like waiting in line at the park or watching the clouds slowly move, your brain isn't as busy. It notices every minute passing because there's not much going on.

When you’re having fun, your brain is working hard to remember all the cool things that are happening around you. It’s like taking a photo of every happy moment. That uses up lots of energy and makes time seem shorter.

But when you're not having fun, your brain isn’t busy, it just notices how long everything takes. That's why time feels slow when you’re not enjoying yourself.
