In a special episode recorded in front of an audience at the BBC Radio Theatre in London, What's up Docs? explores the wonders of the human heart.

"The heart is more than just a pump- it's a marvel of engineering and history, and in this episode, we're pulling it apart to see how it all works!”

Join Drs Chris and Xand van Tulleken as they discover how reliable the human heart can be, beating on average a hundred thousand times a day - that's more than 2.5 billion beats in a lifetime!

The doctors are joined on stage by two guests - Sian Harding is Emeritus Professor of Cardiac Pharmacology at the National Heart and Lung Institute, Imperial College London. She is also author of the book “The Exquisite Machine: the new science of the heart”. Also taking part is Professor Stephen Westaby, one of the world's leading heart surgeons. Over the course of his career, he has performed over 11,000 heart operations and is renowned for his ground-breaking work in artificial heart technology.

Together they'll look back at the history of heart surgery, reveal some of the latest breakthroughs in heart science and surgery, including the future of artificial hearts, and discuss how best to look after your own heart.

Are You A Charlotte?

Are You A Charlotte?

In 1997, actress Kristin Davis’ life was forever changed when she took on the role of Charlotte York in Sex and the City. As we watched Carrie, Samantha, Miranda and Charlotte navigate relationships in NYC, the show helped push once unacceptable conversation topics out of the shadows and altered the narrative around women and sex. We all saw ourselves in them as they searched for fulfillment in life, sex and friendships. Now, Kristin Davis wants to connect with you, the fans, and share untold stories and all the behind the scenes. Together, with Kristin and special guests, what will begin with Sex and the City will evolve into talks about themes that are still so relevant today. "Are you a Charlotte?" is much more than just rewatching this beloved show, it brings the past and the present together as we talk with heart, humor and of course some optimism.
