Records
Tamaki's record is a strange and specific one, and that is what makes it hers. Guinness certified her as the world's oldest office manager in November 2020 at 90 years and 174 days, a title nobody else held at that moment. The number that matters more is the tenure: more than 65 years at the same company in the same position, closing in on 70. Plenty of people hold records for speed or size. Hers is for staying, and for staying useful. She has outlasted the abacus, the fax machine and several generations of colleagues, and she is still managing staff at 95.
