Today on The Gist, Maria Konnikova of the New Yorker returns for another installment of "Is That Bullshit?" Maria and Mike take a closer look at compression sleeves used by elite athletes, senior citizens, and injured folks alike. Plus, we talk about the U.S. military's Massive Ordnance Penetrator bomb and Russia's Armata supertank with Rebecca Grant, the president of IRIS Independent Research and a contributor to Air Force magazine. For the Spiel, Mike raises an eyebrow at the body count in Avengers: Age of Ultron. Today's sponsor: Squarespace, the easiest way to create a beautiful website, blog, or online store.
