I work in an office. wash my hands constantly, eat healthy, get lots of sleep. how else can i prevent getting sick this winter ie cold/flu?

To Avoid Flu: Wash your hands before touching your eyes, nose or mouth. Wash with warm water & soap for 20 seconds. Use paper towel to turn off faucet & open door when exiting a public restroom. Antiseptic wipes can be used on doorknobs, keyboards & other surfaces. Stay away from people who are ill. To avoid flu – get your flu shot each year.
