Yes, a bit of math. (after all, this is backstage, right?)

If you have a child, and your child is (approximately) 1 year old and you are 30. That's a 1/30 ratio.
When your child is 30, you will be 60. That's a 1/2 ratio.
When your child is 60, you will be 90. That's a 2/3 ratio.

So as you and your child grow (and if you could grow for a VERY long time), you would reach a 1/1 ratio.. or the same age!

Aaaaaaaand? What's the deep since of this calculations?

The sense is that ff you are 40 and the human right activists protest in front of your house you can show them that a 10 year old bride isn't that much to worry about.

only once you are infinity years old

It is a simple mathematical formula:

lim { n -> +inf } (x / (x+n)) = 1

If you think about it, it's easy to distinguish a 10-year-old from a 1-year-old. But less easy to distinguish people's ages when they get up in age a bit. (not always difficult, of course, but sometimes it's possible to miss by many years)

Another interesting reflection: Carl Sagan in one of his famous Cosmos episodes, commented that, not only is there always a number greater than (x), but that all numbers are equally far from infinity!
