This week we look at why and how we preserve people and things. We learn how argon is used to protect historical documents, and we interview Ronn Wade, director of the Maryland State Anatomy Board. Wade tells us about plastination, a modern-day mummy, and how to secure and preserve cadavers for medical students. And producer Eric Mack visits Nederland, Colorado, for Frozen Dead Guy Days where cryogenics and cryonics are discussed very seriously. Element of the Week: Argon.
