Watch this Video by the U.S. Centers for Disease Control & Prevention (CDC), and learn how to wash your hands properly. Scientists estimate that up to 80% of all infections are spread by hand contact, and could be avoided by washing hands often enough and well enough. Harmful germs can live on almost everything, from doorknobs to animals to food. The CDC advises that “hand washing may be your single most important act to help stop the spread of infection and stay healthy.”
