Have you ever stopped to wonder what benefit that spider crawling across your bedroom wall brings to your home? Or how your wet, muddy dog contributes to the microbial communities living on your couch — and in your gut?
On this episode, Andrea talks to Rob Dunn about how everything from water filters to sourdough bread inform what’s taking up residence within your four walls. Rob is a researcher who studies the biology of daily life, and is the author of five books, including his most recent, award-winning title “Never Home Alone.”
The two dive into why most “spider bites” are actually something totally different (hint: it’s microbe-related!) and why it’s important to let certain creepy crawlies live inside. At the end of this episode, you’ll be looking at your shower head and your floorboards in a whole new light.
