The Curiosity Desk

First up, Edgar interviews Dr. Jim Faust about his nonprofit Adam’s Parachute, bringing people suffering from substance addiction into the world of fly fishing. He’ll join alongside GBH report Craig LeMoult ahead of Craig’s forthcoming reporting. 

Then, the grocery aisles are packed with all different options for salt. Table, iodized, sea, Celtic, gray, pink Himalayan – does it matter which you use? We get some consult from Dan Souza from America’s Test Kitchen. 

Lastly, Edgar brushes up on the history of the toothbrush with Dr. Scott Swank, curator at the National Museum of Dentistry in Baltimore.
