How to slash your dementia risk in 12 weeks
Around the world, more than 50 million people are living with some form of dementia – a number expected to triple by 2050 as populations age. But the thing is, dementia is often talked about as a kind of genetic lottery. You either get lucky and escape it, or unlucky and develop it. But what if that framing is wrong? What if far more of our brain health is within our control than we’ve been led to believe? Our guest today is Dr Majid Fotuhi, a neuroscientist who has spent decades treating and studying people with cognitive impairment. His message is a bold one: dementia is largely preventable – not with a miracle pill or silver-bullet treatment, but through the way we live. The 12-week programme he and his team have developed has helped his patients improve their memory, regain independence, and even grow new brain connections. Today, he talks us through the essentials of the programme – and what it really takes to stay sharp for life. Learn more about your ad choices. Visit podcastchoices.com/adchoices
Why connecting with others is vital for our mental health
Statistics show that half of us will experience a mental health condition of some kind by the time we turn forty. Could this be due to the increasing pressures and looming crises we’re currently facing in the modern world, overstimulating natural responses in our brains and bodies that have evolved over hundreds of thousands of years to protect us from threats? In this episode, we’re joined by Dr Joanna Cheek, a psychiatrist, psychotherapist and clinical professor based at the University of British Columbia’s Faculty of Medicine, to talk about her latest book, It’s Not You, It’s the World – A Mental Health Survival Guide for Us All. She tells us how the system of alarm signals in our brains is being increasingly triggered by the rapidly changing circumstances we find ourselves in, how this is hijacking the push and pull of our natural risk/reward systems, and why connecting more deeply with the rich tapestry of the people and cultures we share the world with can help us all bring our lives back into balance.

How metabolism really affects your health, weight and wellbeing
Whether we’re working at a desk in an office, running a marathon or even asleep in bed, our bodies are host to thousands of chemical processes that are continually converting the food we eat into energy and repairing our bones, muscles and organs. Collectively these processes are known as the metabolism. But how are they affected by our genes, lifestyles and diet, and what can we do to make sure everything stays running smoothly? In this episode, we’re joined by Javier Gonzalez, a professor of nutrition and metabolism based at the University of Bath. He breaks down the links between our metabolisms and body types, tells us why our metabolisms aren’t necessarily fixed for life, and explains why it’s almost impossible to out exercise a poor diet if you’re looking to drop a few kilos.

What faces reveal about us and the societies we live in
The human face contains more than 40 muscles, giving us an ability to visually express our thoughts and emotions that is unique in the animal kingdom. This has perhaps led to a long-held obsession to uncover the many mysteries of our faces that has persisted in everyone from artists, scientists and even anthropologists for thousands of years. But where is this trend heading? And is it doing more harm than good? In this episode, we’re joined by Dr Fay Bound-Alberti, the founder of the Centre for Technology and the Body at King’s College London, to talk about her latest book, The Face: A Cultural History. She tells us how the idea of the perfectly proportioned face that began in classical art continues to persist in today’s social media beauty trends, the various attempts that have been made over the years to determine a person’s good or bad qualities based on their facial characteristics, and explains the challenges we’re currently confronted by thanks to the rise of new technologies such as facial recognition.

How AI could help us create life from scratch
For the last several billion years, all life on Earth has progressed according to the rules of evolution by natural selection – a step-by-step process that has given rise to the fascinating complexity and beauty of all the living things we share our planet with. But now, due to advances in our knowledge of genetics and the rise of artificial intelligence, we’re on the brink of being able to design living organisms from scratch. This new field of research is known as generative biology. In this episode, we’re joined by Adrian Woolfson, a researcher who specialises in synthetic genome design, to talk about his latest book On the Future of Species – Authoring Life by Means of Artificial Biological Intelligence. He tells us how this fascinating area of research is bringing us closer to a genuine scientific revolution that could change the way we think about how life is created, the vast implications that this may have on human health and the health of our planet, and why we all need to be aware of this powerful new technology and its potential.

What happens in our brains and bodies when we fall in love
The chances are that if any of us were asked to describe what it feels like to be in love we’d turn to art, poetry or music to help give us the answer. But what does science have to say about this uniquely human experience? In this episode, we’re joined by Dr Justin Garcia, an evolutionary biologist and sex researcher based at the Kinsey Institute in the US, to talk about his book, The Intimate Animal: The Science of Love, Fidelity and Connection He tells us how the evolutionary history of human pair bonding led to the development of our feelings of love, how and why we seek certain characteristics in our romantic partners, and how our attitude to relationships has altered due to changes in thinking, culture, and technology.

Why gradual change is the true driving force of innovation
Over the past several decades, many technologists and policy makers have sought out huge, disruptive shifts in thinking in almost every area of science, business and commerce in the hope that they’d help to drive innovation forward in giant leaps, one brilliant new idea at a time. But how successful has this been, and should we instead be focusing on a more gradual, incremental approach to innovation that’s based on the steady upgrading of the systems we already have in place? In this episode, we’re joined by Albert Fox-Cahn, a visiting professor at The Centre of Governance and Human Rights at Pembroke College, Cambridge, to talk about his latest book Move Slow and Upgrade – The Power of Incremental Innovation. He tells us why we tend to overemphasise the potential impact of the Next Big Thing, how this often leads to a rush to adopt unproven, and at times, unsafe new technologies, and how applying evidence-based thinking and an upgrader’s mindset can help us to be more like the tortoise than the hare, and ultimately win the race.

Why we need to rethink our concept of evil
If most of us are put on the spot and asked to name acts that we think would define a person as evil, it’s likely our minds would turn to murderers, rapists and war criminals, to name a few. But could it be that this commonly held conception of evil isn’t merely just an oversimplification, but rather a deeply flawed way of viewing the world based on a litany of personal biases, and one that is dire need of readdressing? In this episode, we’re joined by Dr Julia Shaw, a broadcaster, best-selling author and psychologist based at University College London to talk about the nature of evil. She tells us why it’s vital that we accept that, given a certain set of circumstances, we’re all capable of committing terrible acts, explains the key differences between thought and action, and explains why so many of us are fascinated by true crime documentaries and dramas.

The hidden ways the Internet and social media are shaping healthcare
From famous actors and pop stars to the legions of social media influencers with millions of views, it seems almost everyone has something to say about the best ways to boost our health and wellbeing. But is this trend leading to many of us bypassing traditional sources of health advice and care such as GP practices and government health services and instead turning to the Internet, social media and private online pharmacies to seek out information, diagnoses, and, in some cases, even prescription medicines? In this episode, we’re joined by Deborah Cohen, an award-winning medical broadcaster and author to talk about her latest book, Bad Influence – How the Internet Hijacked Our Health. She tells us how the COVID 19 pandemic kickstarted a worldwide boom in consumer healthcare that shows no sign of stopping, why celebrities and social media stars hold so much influence over important decisions that can hugely impact our lives, and points out some of the red flags we can look out for when searching for health advice online.

How to break free from the negative cycle of overthinking
While the human mind is capable of great insight, original thoughts and acts of tender kindness towards others, it can also, at times, act like our own worst enemy. Feelings of worthlessness, shame and disappointment can all stem from our brain’s natural inclination for overthinking. This can give rise to a wide range of debilitating impacts on our lives, such as low self-esteem, anxiety and depression and can even lead to the development of significant physical health issues. So, why do our minds seem to sabotage us in this way and what measures can we take to free ourselves from the common traps that lead us to being stuck in endless loops of negative thinking? In this episode, we’re joined by Dr Jessamy Hibberd, a clinical psychologist and best-selling author, to talk about her latest book, The Overthinking Cure – How to Free Your Mind and Focus on What Really Matters. She tells us how common habits such as self-criticism, comparing ourselves to others, and actively avoiding our problems can all lead us to overthink, why we are all vulnerable to getting stuck in spirals of negative thoughts, and how learning to manage where we place our attention is often the first step we can all take to help us to boost our moods and wellbeing.

How paleoartists bring dinosaurs to life
From the terrifying, hulking beasts portrayed in blockbuster movies to the friendly, charismatic characters often found in children’s cartoons, dinosaurs have made their way into almost every corner of popular culture. However, in terms of scientific accuracy, such depictions tend to leave a lot to be desired. So, how do we know what dinosaurs really looked like, whose job is it to show us, and how exactly do they go about it? In this episode, we’re joined by Dr Mark Witton, a researcher, author and highly regarded paleoartist based at the University of Plymouth. He outlines the detailed scientific process paleoartists follow to bring these ancient beasts to life as realistically as possible, runs us through some of the common mistakes Hollywood directors make in the name of artistic licence, and explains why the T.Rex is one of his favourite dinosaurs to draw.

The hidden scoring systems running our lives
In the world of games, scoring systems establish a framework that provides us with clear challenges, motivation, and ultimately delivers a huge amount of fun and pleasure. However, on the flip side, the increasing tendency to apply rankings and metrics to almost every area of our personal and professional lives can have a dehumanising effect, reducing our actions, performance, and even ourselves to a simple string of numbers. In today’s episode, we’re joined by C Thi Nguyen, a games researcher and associate professor of philosophy based at the University of Utah, to talk about his latest book, The Score – How to Stop Playing Someone Else’s Game. He explains how, in the real world, scoring systems typically fail to provide meaning by focusing on the simplest to measure outcomes, how purely numerical data is, by definition, lacking in nuance, and how, by concentrating on what we truly value, we can all break free from the tyranny of rankings and metrics.
