Science explains why some cleaning methods work better than others, and that we do not need to purchase multiple cleansers when a few basic ingredients from our pantry and our local pharmacy can get the entire house spic and span.
Dr Xand Van Tulleken is single and looking for love. Mathematician Dr Hannah Fry wants to use him as her guinea pig to test whether the algorithms that dating sites use to match people actually work. While Hannah builds a dating site, Xand meets the scientists investigating online dating - and learns what pictures to use and what to write in his profile. He tries out a 'bot' that has automated a swiping app and has an MRI scan to find out whether his brain is equipped for love. 50 members of the public take part in some mini experiments at a date night - and Xand goes on various dates to test whether the algorithm is better than him choosing randomly.
Dr Kevin Fong makes a personal journey through the moral questions about death that face not just the medical profession, but each and every one of us. The question of how we die is a question that all of us must face, and yet we avoid talking about it. Modern medicine is focused on saving lives. Amazing technical advances have increased doctors' ability to treat a wide range of life-threatening diseases, meaning many more people live longer lives. Life expectancy has surged, and we regard death as something to be battled. It is common for the medical system to throw everything into treating patients right to the very end. But in our attempts to defeat death, the question is this - are we over-medicalising death and the final years of life at the expense of providing better palliative care that would result in a better quality of life? Is it time to reset the system, and learn how to die a better death? Kevin meets medical professionals who are at the heart of these dilemmas, as well as people who are right now facing up to the question of how to die a better death.
What motivates us to work? Contrary to conventional wisdom, it isn't just money. But it's not exactly joy either. It seems that most of us thrive by making constant progress and feeling a sense of purpose. Behavioral economist Dan Ariely presents two eye-opening experiments that reveal our unexpected and nuanced attitudes toward meaning in our work.
