Heart disease is the leading cause of death in the United States: More than 600,000 people die of heart-related illnesses every year, according to the Centers for Disease Control and Prevention. February is American Heart Month, the perfect time to make lifestyle changes. Walking is one of the easiest ways to reduce risk of the killer disease. If you prefer companionship, the Florida Trail Association develops and maintains a network of hiking trails and hosts regular walks. To carve your own or search for walking paths throughout Palm Beach County ranging in difficulty from easy to moderate, visit the American Heart Association’s startwalkingnow.org.
