I do enjoy it, but you can see how it compares poorly to other alternatives for the very youthful. Particularly for women.
But this is not the point - it isn't even a conscious decision for the most part to have kids late. Modern life is just set up that way. None of my peers were having their first kid at 20. None of my peers were even in a serious relationship at 20. Most weren't in any sort of relationship.
You don't think you could enjoy raising offspring of your own?
