"Did you know astronauts train in water before going to space? They are not the only people who do. Athletes and doctors use pools, too. Athletes train in water when they are hurt. Doctors use water treatments to help people who are sick feel better. Water and pools are not just for swimming when it is warm."-- Provided by publisher.
