Swimming saved his life: Iowa high school coach, 91, beats COVID

DES MOINES, Iowa – It's early on a June day as Tom Cady sits in the living room of his home. He's waiting for his first lesson of the day, and you can tell he's ready by how he's dressed: Iowa shorts and Hawkeyes swimming shirt. 

He's a 91-year-old swimming instructor who has taught the skill to Des Moines metro children since his teens. Most of those lessons came in the pool at his home. Very little has stopped him from his life's mission. He can recall only three stretches when he's been away from teaching swimming.
