Math Problem

How is it that when my first daughter was born, I was 25 times older than she was?

But when she was 5, I was only 6 times as old she was (30)?

It gets worse, or better depending on how you look at it.

When she was 25, I was only twice as old as she was (50).

If my math is correct, when I'm a 100, I think all three of my daughters will be older than I am. It's about time.
