Are coins the dirtiest objects on Earth?
Could you elaborate on the claim that coins are potentially the dirtiest objects on Earth? Given the frequent exchange of hands and potential exposure to various environments, it seems plausible that coins could harbor a significant amount of bacteria and germs. However, are there scientific studies or evidence to support this assertion? Additionally, how do coins compare to other commonly touched objects, such as mobile phones or keyboards, in terms of their potential to harbor harmful microorganisms? Understanding the science behind this claim would help us assess its validity and determine the appropriate hygiene measures to take.
