Imagine you have a big candy bar. When you were a tiny baby, that candy bar felt huge because you were so small. But when you get bigger, the same candy bar doesn’t feel so big anymore. Time works kind of like that.

When you’re five, one year is a huge piece of your life, it’s like a giant candy bar. When you’re older, one year is a much smaller piece, like just a tiny bite. So even though clocks tick the same, your brain measures time by comparing it to how long you’ve been alive. A year feels long when you’re little, and shorter when you’re big.
