Which is better: Soap or hand sanitizer? | Alex Rosenthal and Pall Thordarson - a podcast by TED

Your hands, up close, are anything but smooth. With peaks and valleys, folds and rifts, there are plenty of hiding places for a virus to stick. If you then touch your face, the virus can infect you.

[Directed by Artrake Studio, narrated by Addison Anderson].
