Poor, Marguerite Joseph. She’s 104, which is really something to be able to crow about and be able tell all her Facebook buddies. But she can’t, because the Michigan woman is unable to post her actual age on the site — because it exceeds 99.Since the Grosse Pointe Shores centenarian is legally blind and hard of hearing, her granddaughter Gail Marlow has been updating her profile page each day for the past two years, and responds to her messages.Marlow says that when she tries inputting her grandmother’s birth year as 1908, Facebook changes it to 1928 with a message that says ‘unknown error.’Marguerite Joseph, forever 99 — at least on Facebook.
