Would a popup asking for year of birth be sufficient? The popup could check if the year was not good enough and ask for month and if that wasn't good enough ask for the specific day. That way, the popup would be less discouraging the farther you are from violating the age restriction, but more discouraging the closer you were, which is probably a good thing.
