When it comes to successful online dating, the two things that seem to matter most are your screen name and your profile picture. I begin this episode by explaining what works best as determined by researchers who reviewed thousands of online profiles of people who were successful online daters and people who failed miserably. http://www.sciencedaily.com/releases/2015/02/150212212100.htm What determines your behavior? Is everything you do the result of your free will or is your behavior determined by something else? Could it be you are not responsible for your own actions? Robert Sapolsky, a professor of biology and neurology at Stanford University joins me to make the case that we are not responsible for what we do – that it is determined by all sorts of biological influences. What he says will either make you a believer – or make you crazy. Robert is the author of several books including the bestseller, Behave: The Biology of Humans at Our Best and Worst. https://amzn.to/2LWQRZR Do you know what you look like – really? You’d think so but actually other people are probably better than you at identifying photos of you that REALLY resemble what you like you. Sounds odd, right? We shall explore why that is and why your self-image may be somewhat distorted. http://www.alphagalileo.org/ViewItem.aspx?ItemId=154010&CultureCode=en Are we too obsessed with being clean? Are we over-sanitizing our world? It looks like it. Marie-Claire Arrieta, assistant professor at the University of Calgary in Canada is co-author of the book Let Them Eat Dirt: Saving Your Child from an Oversanitized World https://amzn.to/2vj6r7S . She joins me to explain the unintended consequences of keeping our homes, our children and everything else in our lives TOO clean. Those consequences include an increase in asthma, allergies, resistance to antibiotics and much more.
