We’ll kick off the season with some of last year’s viewers’ favorites, starting with Gracey’s visit to the lab of a medicinal chemist to see how he researches ways to develop new medications that will benefit people with cancer and diabetes. Then we’ll take a look back at Shawn’s meeting with a lobbyist and learn how she advocates for causes to get laws passed. Plus, we’ll bring you Gracey’s interview with an Orthopedic Surgeon and see why he enjoys fixing people’s broken bones and other muskulo-skeletal issues.
