Great article about health. Summary: Do not touch any part of your face and do keep your hands clean. It turns out you can make yourself sick more easily if you touch any part of your face or you fail to wash your hands after touching things before you eat or touch your face. Avoid things and situations that can encircle your face or hands with an unnecessary abundance of sick causing agents. Don’t scratch. If your hands, face, nose, or ears itch, just wash them with clean water and soap. Yeah, easier said than done.
