Have you ever noticed that time seems to fly when you're having fun but feels slow when you're bored? That's because your brain doesn't experience time like a clock does. Instead, it estimates time based on how much attention you're giving to an activity. When you're busy or enjoying yourself, your brain pays less attention to time passing.
When you're waiting or doing something repetitive, every minute feels longer. This is why a five-minute wait can feel like forever, while a two-hour movie can seem surprisingly short. Your brain controls how long time feels, even though the clock never changes.
