Good morning. I'm Noel King with the story of a boy nicknamed Superman. Clark Kent Apuada is a 10-year-old swimmer. Over the weekend, he shattered a record in the 100-meter butterfly that was set by Michael Phelps back in 1995. Phelps, the most dominant swimmer in years, is known for his obsessive focus on swimming. Clark Kent is a little different. He also is into martial arts, science, computer coding, and he plays the piano. Hey, if the nickname fits. Transcript provided by NPR, Copyright NPR.
