This week's episode is about washing your hands, maybe obsessively, definitely prophylactically, probably more than most people. Lindsay Robertson, an expert practitioner of hand sanitizing on the go, joins us to talk about what to do when there's no soap and how to stop a sneeze when you feel one coming on. We also discuss antibiotics, probiotics, and how most "food poisoning" is probably just food-borne norovirus. Gross stuff.
