How did you fall in love with your favorite team or teams? Are you a fan of multiple teams in the same league? Do you always root for the underdog?

Anthony interviews his daughter Isla and Edward Hirt, who is a professor of Psychological and Brain Sciences at Indiana University, to find out some of the psychology behind sports fandom.
