Why Does Time Seem to Speed Up When You're Having Fun?

Imagine you're at a birthday party, the cake is cut, everyone is laughing, and time feels super fast. But when you're stuck in a long meeting, it feels like the clock is moving slower than usual. This happens because your brain pays more attention to fun moments, making them feel shorter. Time doesn’t actually speed up or slow down; it’s all about how much your brain focuses on what’s happening.
