My mother always told me that money is really dirty and I should wash my hands after handling it. It was a case of “you don’t know where that’s been”. It turns out, as usual, that she’s right. Really right. Scientists gathered 68 dollar bills and found disease causing bacteria on 94% of them. 93 species were identified. 7% of the bills had really bad stuff like pneumonia. This shouldn’t be cause for alarm, but I do think I’ll wash my hands after counting up the lunch check now.
