What are some of the changes that happened as a result of the Black Death?

The Black Death was a plague that ripped through much of Eurasia and Africa beginning in the early 1330s and lasting for 20 years. Death tolls in various countries ranged from 30 to 80 percent and changed that part of the world so dramatically that we still feel its effects today, 700 years later. What were some of these changes? This episode explores a few of them, both the negative and the occasionally surprising positive. Warning: you might never view lasagna the same again.
