If you are close to retirement age (65), are you getting a bunch of e-mail junk and regular post snail-mail about Medicare? Every few weeks now I get in USPS mail 'official' looking correspondence, only to find once I open the envelope it's from a non-disclosed 'party' with a PO Box somewhere in the middle west. How the heck are these 'nameless' entities finding out who is close to 65? (I think I know the answer, wondering if you've come to same conclusion).
