We often ask that question when others are baffled about decisions. And there may be more wisdom and influence living in that gut than we realize.

As a college sophomore, Elaine Hsiao learned in microbiology class one’s gut holds almost twice our brain weight in bacteria. For what purpose? As a graduate student Hsiao learned that these bacteria might actually influence our thoughts, moods and behavior.

Now a research fellow, Hsiao explores how those microbes can affect brain function. Perhaps she is on a path of healing; perhaps one day we treat mental health by simply introducing more microbes into one’s system.

My gut tells me such a discovery would bring peace and wholeness to millions.
