Thanks to everyone for the information posted here
I want to add something I was surprised to learn a few years ago - at a youth science fair actually. Always learning from little kids! - re hand washing -
Avoid touching your eyes, nose or mouth.
Germs are often spread when a person
touches something that is contaminated
with germs and then touches his or her eyes,
nose or mouth.
I'm a notorious eye-rubber. I guess picking one's nose could be hazardous too.
