Helen, a 30-year-old white rhino, wears a fitness device on her right front leg as she walks around on the savanna at Walt Disney World's Animal Kingdom theme park, Monday, May 16, 2022, in Lake Buena Vista, Fla. The purpose of the fitness device is to gather data on the number of steps she takes each day, whether she is walking, running or napping, and which part of the man-made savanna she favors the most.
