Listener Piper called us up with this question, “Why do some people have a harder time than others distinguishing their left and right?” When our friends at the Vox podcast Unexplainable heard it they were so intrigued that they created a whole game show around it and invited our very own Explain It to Me host Jonquilyn Hill to play along. Why do some people struggle to tell their left from their right? What makes someone a lefty? And why does life have this weird rule about only having either left- or right-handed molecules?  Check out Unexplainable wherever you get your podcasts.
