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

Time feels like it goes faster when you're older because you have fewer new experiences. Imagine playing with your favorite toy, that feels super long. But if you've played with the same toy every day, it doesn’t feel as exciting anymore. Your brain notices changes more clearly when you’re younger, so time seems to stretch out. When you get older and things change less often, time feels like it’s going by in a blur.

When you are little, everything is new: your first day of school, your first bike ride, meeting new friends. These all make time feel slower because they’re exciting and different from the usual. But as you get older, most things become more familiar, like going to school or hanging out with friends, so time feels like it's moving faster.
