In 1968, the American Heart Association made an announcement that would influence people’s diets for decades: they recommended that people avoid eating more than three eggs a week. Their reasoning was that the cholesterol packed into egg yolks could increase cardiovascular disease risk. So, what exactly is cholesterol? And is it actually bad for you? Hei Man Chan digs into this complex molecule. [Directed by Igor Ćorić, Artrake Studio, narrated by Addison Anderson, music by Cem Misirlioglu].

After the talk, Shoshana interviews Dr. Eric Topol, a cardiologist and founder of the Scripps Research Translational Institute on AI, genomics, and the digital tools that are revolutionizing the way we prevent, detect, and treat illness—including heart disease.

After a mysterious wave of tics and twitches swept through a small-town high school in New York, documentary podcaster Dan Taberski set out to investigate what was really happening. Drawing on extensive research and intimate interviews with the people involved, he explores the roots of mass hysteria — and what it reveals about the line between illness and belonging. What happens when the very thing that makes us sick ... is also what connects us?

After the talk, Shoshana interviews Dan on how his research into the mysterious Havana Syndrome leads to his unearthing of a similar mass hysteria in Le Roy, New York. They also discuss how storytelling can reshape discourse surrounding medicine and what happens when the person experiencing an illness feels unheard and unsupported by the very medical professionals supposed to care for them?

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? When it comes to defining “normal,” data journalist Mona Chalabi isn’t interested in averages: she goes beyond the spreadsheet and digs into the deviations, talking to experts, strangers (even her Mum!) to see the bigger picture. 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.
