What's makes you think I'm interested in storing the distinctions?
Either I know the birthday or I don't. If I want to work out why I
don't know it, yeah, it's worth storing the state. There are other ways
of finding that out (for example you can readily tell if you're looking
at a business and I know the system doesn't have people that aren't
born yet). But mostly I just need to track that it's not known.

Have a nice day,
