I turn 50 next month, and lo and behold, AARP has sent me an invitation to join. I have not filed a USPS change of address, they couldn't find me if they had an old address. My bank, the Marlyand Department of Taxation (as I am the registered agent for Viridian Development Corporation), the whois for paul-robinson.us, the Motor Vehicle Administration, Prince George's County Registrar of Voters, Prince George's Welfare Office, Social Security and my credit union are the only places that have my address, and MVA is the only one that has my date of birth for my Drivers' License (I doubt AARP is getting voter registrations).

So I think AARP is collecting Drivers' License info.
