A 101-year-old woman in New York is still working a weekly job, living alone, and outpacing people decades younger when it comes to staying sharp. According to a report by TODAY.com, Eileen Lavine credits her long, active life to three habits, and not one of them involves exercise. Old age is usually pictured as a slow fade, naps, forgetfulness, fewer plans on the calendar. Lavine's routine, however, tells a very different story. At an age when many people struggle to recall what they ate for breakfast, she is still copy-editing professional publications, working through a stack of newsletters, and keeping a social calendar packed enough to tire out younger relatives. Her core belief, per the report: a mind kept busy ages very differently from a body left idle.
