Last week I told you about 114-year-old Besse Cooper of Georgia, who Guinness World Records has named the world's oldest person. Turns out Besse has some competition for the title: The family of Rebecca Lanier of Ohio claims she just turned 119. Problem is, Rebecca has no birth certificate, so Guinness won't recognize her claim. (Rebecca is African American, and her family points out that birth certificates were not always issued for African Americans born in 1892.) Maybe Besse and Rebecca should just duke it out, UFC-style! Anyway, don't worry: I will be following this story very closely and providing regular updates.
