Show Notes * 'Surface-based Body Shape Index', which takes into account distribution of body weight, has been found to more accurately predict mortality than the Body Mass Index (BMI). * Teachers who use humor in their classrooms tend to get better student evaluations by their students, regardless of learning outcomes. * Squatting down makes it quicker and easier to poop as compared to sitting down, probably because sitting upright leaves a kink in the gut that straightens out when we squat. * Accurate science or accessible science in the media – why not both? * Squatty Potty
