If two people were born one after another with one second difference,

and one of them is a child, then the other one is a child too.

We get by induction that all the people are children.

Provided that you can prove that from a time onwards, there was  at least one baby born in every second.
پاسخ:

Let P be the set of people , and W be a set including P and for each second in which we don't have a baby in P there is a baby in W.
Now our induction is correct on W as we have a baby for each second. so all the elements in W are children.And finally any subset of W (just like P ) is only consists of children.

With the same idea, we can prove everyone is old. Contradiction!

So I guess most definitions are bendable in reality
