You know that one of the most important things you can do to avoid catching a cold or the flu is to wash your hands frequently. The problem is, most people concentrate on washing their palms – when it’s the fingertips that really matter. Dr. Neil Schachter is a respiratory specialist at Mount Sinai Medical Center. And he says our fingertips are more likely to come into contact with germy surfaces – and we’re most likely to stick a fingertip in our mouth, nose or eyes, the main entry points for germs. So when you wash your hands, make sure you focus on those fingertips!
