I'm shocked that Googs does not already have enough information collected and linked to your account that this is necessary. Maybe FB can create a service where you can submit an email/phone number, and then return the age of the user. You know between the Googs and FB, they have linked to your profile multiple emails so I'm betting it would be a pretty robust service. Of course returning the user's age would be the lowest tier offered. For a higher service fee, you could then gain more access to the user. CASH COW
