What are you: an introvert or an extrovert? Russell Kane is a comedian, so he has always assumed he's a textbook loud-mouthed extrovert. But now he's not so sure.

Across this series of interviews, Russell explores exactly what we mean by the terms "introvert" and "extrovert". He questions whether it is useful to define people in this way and whether we have a cultural bias towards one personality type over the other.

In this second of three parts, Russell talks to author Jessica Pan about her year of "living dangerously" as an introvert pretending to be an extrovert in order to open up her world. What did she learn? How did it change her? And what advice does she have for other naturally introverted people?
