Public radio and podcast audiences have been listening to Lulu Miller’s storytelling for years on Radiolab and on Invisibilia, a show she co-founded. Her work is generally about other people but on this episode, she shares her own story, which is by turns harrowing and triumphant. Lulu’s new book is “Why Fish Don’t Exist” and it’s about her history with depression, the scientific curiosity that helped get her back on track, and, yeah, why fish don’t exist.
