Josh Schroeder Posted almost 3 years ago Probiotics, like yogurt, are known to support healthy gut microbes. How could we apply this idea support a healthy house, subway, or office? If we're looking at the probiotic idea in the abstract... Let's look at a definition of probiotic (which I grabbed from Wikipedia): According to the currently adopted definition by FAO/WHO, probiotics are: "Live microorganisms which when administered in adequate amounts confer a health benefit on the host." So you A) introduce something B) in sufficient supply, in order to C) benefit D) the host. Perhaps using this rubric can help us ponder the topic of conversation: Who or what is the host? What is the desired benefit? What or who is introduced to convey the benefit? And how much or how many people are needed to make it happen?
