Today, a trailer from Am I Normal? with Mona Chalabi, a new TED Original podcast. ​​Everyone wants to know if they're normal. Is my body normal, is my brain normal, are my feelings normal?

Along the way, she will tackle urgent, random and sometimes deeply personal questions: How long does it take to heal from heartbreak? How many friends should I have? What makes “good” sperm? And does normal even exist? Subscribe to Am I Normal? wherever you're listening to this.
