When Muriel Johnston retired from her job as an office manager, she applied for a Peace Corps posting. Other retirees apply, but Johnston was 84 at the time. She was accepted into the Corps and headed off to Morocco, working for two years as a health and hygiene educator in a remote and primitive rural village. Known there as "the toothbrush lady," she also taught English, and created a school library. One of her astonished sons said, "Her early life gave little hint of her more adventurous old age." Five of her six children approved when she told them she was heading to her overseas post; the youngest one asked why she couldn't just be normal. Johnston smiled and headed for the plane.
