A 100-year-old Japanese woman set a new record Monday when she became the first centenarian to complete a 1,500-meter freestyle swim. Mieko Nagaoka did the race in just over an hour and 15 minutes—especially impressive given that she only took up swimming at age 80. Her goals are modest: “I want to swim until I turn 105 if I can live that long,” she told the Kyodo News.
