This is a formal request for all Disaster Hour listeners: Please wash your hands after defecation, urination, and all other bathroom activities. In this one, Ian and Liv talk about the case of Mary Mallon, aka Typhoid Mary, who was a silent carrier of typhoid fever in the early 1900s. Spoiler alert: hand washing could've saved lives. Literally.

Also, Liv was a disease-ridden child. Ian is still playing Lego Fortnite.
