Why do we kiss?

In this BBC Radio 4 podcast, Drs Chris and Xand van Tulleken are on a mission to help us take better care of ourselves.Although they are identical twins, Chris and Xand are very different and they never stop thinking and arguing about science and health. They want to lead healthy, happy lives and as doctors, they want this for everyone. Yet they tussle over how best to get there.When it comes to looking after our own health, it can be confusing. Medicine and science produce amazing new treatments and diagnostics every day and we are bombarded with so many headlines and pieces of advice; but how are we supposed to know what's really best for us and then successfully apply it to our lives?Drs Chris and Xand van Tulleken embrace this challenge; even as they marvel at the scientific breakthroughs, they grapple with the competing claims about health, wellbeing and how to live.From understanding testosterone therapies to microplastics in our diets, and the concept of 'hangriness' to the power of saying no - this podcast deals with the health stresses we all face every day, while taking on board how the decisions by corporations and governments affect all our health.Each episode, Chris and Xand are joined by an expert guest to examine the latest research, psychological insights, and data, to help listeners navigate the overwhelming amount of information and advice out there. They talk about the trials and tribulations in their own lives in their characteristically witty way - each teasing the other as they search for solutions. Xand has trouble sleeping , Chris has noisy knees, one of them has got an embarrassing itch. They have different ways of looking at things and find it really helpful to get the other one's point of view. These doctors are trying their best and encouraging listeners to do the same.Email: whatsupdocs@bbc.co.uk
