I No Longer Am Older than Myself

I received a replacement American Express card in the mail.  Ever since my father first got me one (affiliated through his account) for my high school exchange trip to Spain, the front of my card proudly proclaimed "Member Since '67" -- four years before I was born!  The new card, however, replaced 1967 with 1988.  The bills still will go to my mother, though -- won't they?
