        Whose Air Do You Share? | It's Okay to Be Smart | PBS Digital Studios

        Here's an amazing thought: every time you breathe, you could be sharing air with everyone who's ever lived. A few million of the same air molecules that enter your lungs in a lifetime also entered Albert Einstein or Marie Curie's lungs! That's some smart air. All the air that keeps us alive is just a thin candy shell around our planet. In this episode, echoing the words of John F. Kennedy, Joe Hanson, host of It's Okay to Be Smart, shows you the science of how we all share the same air.
