This is a fun look at a serious problem - germ transmission.  When I visit at the hospital I try to remember to wash my hands before going into a patient's room and after leaving.  A nurse once told me that to get the best effect I should wash my hands for as long as it takes to sing happy birthday.  After a few strange looks I now sing it in my head.

If we all celeberated more birthdays in our heads,  fewer of us would get sick from unnecessary germ transmission.  However, it seems that only 4 out of 5 people wash their hands after using the washroom.  How do we get the 5th person on board with good hygiene practices?  Here's a site with some good suggestions.
