So, in talking about his anxiety with me, my brother mentioned that he's always been kind of anxious, but it got suddenly and substantially worse when he was in Mexico for a semester in college, after he got sick and was treated with antibiotics. "Hmm," thought I, "We're learning so much about the symbiotic connection between our bacterial friends and many of our other internal systems..." So I did a quick web search to see if this is something people are talking about at all.

Well, lo-and-behold, it is. It looks like there may, in fact, be a connection between our microbiome and our mental health, and though the factors and relationship are just being discovered and preliminarily explored, it looks kind of fascinating.
