In the final episode of the series, Emily and Amy explore areas of physiology relevant to life in lockdown. They speak to Ben Maylor and Greg Biddle (University of Leicester, UK) about how sedentary behaviour can affect your health, and Susan Lanham-New (University of Surrey, UK) about how life in lockdown could lead to a Vitamin D deficiency.  They also discuss: Which currency is the worst when it comes to spreading bacteria? Will we all come out of lockdown with Rapunzel length hair? And do animals get bored?
