Why Does Time Feel Slower When You're Young?

Imagine your life is a book. When you are five years old, every day is a brand new chapter filled with exciting discoveries like learning to ride a bike or meeting a new friend. Because so much is new, your brain has to work hard to record all these details, making each day feel long and full.

As you grow older, life starts to look more routine. You go to the same school, eat similar meals, and see familiar faces. Because there are fewer new things happening, your brain stops recording every detail as closely. It compresses these repetitive days together like a fast-forwarded video.

Mathematically, five years is half of your entire life when you are ten. But fifty years is only one-tenth of your life when you are fifty. So, the same amount of time feels much shorter because it represents a smaller piece of the whole pie. This is why childhood summers seem endless while adult years zip by.
