When Maria Branyas Morera passed away in August 2024, she was 117 years old, the oldest living person on Earth. Unlike many of us imagine old age, she didn’t spend her last years bedridden or cognitively impaired. She read books, gardened, played piano, enjoyed yogurt and olive oil, walked daily, and kept the company of friends and dogs. Her life was quiet, but her healthspan, the years she lived free from major disease, was extraordinary.
