I just read this:
It takes warm water, soap, and 20 seconds of scrubbing to rid then of cold and flu germs. PS.: While 95% of people say they wash their hands after using a public restroom, only 67% actually do â€“yikes! Of that group just 33% use soap, and only 16% wash their hands long enough to make it count.
Only 16% of people that “think” they wash their hands after using a public restroom do it well enough to have any affect.
Maybe Monk’s faniticism makes sense…
