Swimmer Veronica Simmonds wants to know what happens when you take aquatic adventure to the extreme. So we called up ‘aquanaut’ — that’s like an astronaut but underwater — Jessica Fain, who holds the record for longest time spent living underwater.

She and colleague Bruce Cantrell spent 73 days in the Jules’ Undersea Lodge in Key Largo, Florida doing exactly what you’d expect two undersea landlubbers to do: raising awareness about the wonders of marine biology, leading university-level seminars via Skype, and ordering pizza for delivery. Listen below to find out how. 

The party continues when you subscribe to Completely Optional Knowledge (tea, crumpets and scuba gear not included).
