Your brain is not enoughPosted on July 20, 2017 by Mark Rovner Critical thinking is important, but it’s also over-rated. When faced with choices and decisions, you have at least two equally important sources of wisdom and guidance. First there’s your heart. Second, and surprisingly, there’s your gut. You have roughly 100 million neurons in your digestive system, so much that scientists refer to it sometimes as your second brain. So it turns out when you speak of making gut decisions, that’s not just a figure of speech. Your brain is just one important tool as you navigate your world. Best not to ignore the others.
