What is the Terrain Theory?

What is terrain theory? In this video, during a "Success Interview" on the "Unleash Your Greatness Within" podcast with David Moscow. David Moscow is a film, producer and author. During our conversation, we discussed the importance of a healthy immune system. Jokingly, before this clip in the interview, David Moscow and TJ Hoisington talked about the importance of eating a spoonful of dirt once a week. We weren't being serious (haha), but rather making a point that being exposed to germs periodically may actually help our immune system be stronger. Listen and try to hear the message in the spirit it was given. #Health #Lifestyle #Immunesystem #Germs #Resilience - Watch on YouTube: https://youtu.be/h726X6CGe4I
