According to the Centers for Disease Control, 37 percent of American adults can’t swim the length of a pool, which puts them at risk of being one of the 10 people who drown every day in the United States.
The Swimming Saves Lives Foundation, U.S. Masters Swimming’s charitable arm, has declared the month of April “Adult Learn-to-Swim Month.†That’s when pools, lakes, and beaches are opening up for spring and summer recreation.
