So the results of a study by the London School of Hygience and Tropical Medicine, and Queen Mary, University of London, found fecal matter (yikes) on.....get ready.....credit cards!
In fact up to one out of every ten credit cards. Even worse, one in seven of those bills in your wallet! ("paper or plastic?")
This study was done in London and some 90% claim to wash their hands after using the "loo", so we probably have that same issue here.
So if your work includes handling credit cards...um...maybe use those little plastic gloves?
