This documentary dives into the rapidly expanding world of anti-ageing science and longevity research, following a determined journey to separate bold promises from real breakthroughs. Guided by a curious and questioning approach, it explores cutting-edge laboratories, emerging therapies and the scientists who are challenging one of humanity’s oldest limitations. From biological age reversal to experimental treatments, the film reveals both the excitement and the uncertainty surrounding a field that could redefine how we understand life itself.
As the investigation unfolds, it raises compelling questions about what it truly means to live longer—and at what cost. By confronting the hype, ethical dilemmas and scientific realities, the story offers a balanced and thought-provoking look at a future where ageing might no longer be inevitable. It’s an eye-opening exploration that invites viewers to reconsider the boundaries of human lifespan and the possibilities that lie ahead.

In the final two episodes, the experiment moves from theory to real life as the twins are forced to take full control of their food choices after moving out on their own. Cooking becomes a daily challenge, exposing how habits, convenience, and culture shape what we eat. At the same time, innovators pushing plant-based alternatives step into the spotlight, as growing concerns around animal products raise urgent questions about health and sustainability.
As the study reaches its conclusion, the results are finally revealed. Detailed analyses of weight, gut health, and brain function confront the twins with clear, and sometimes surprising, consequences of their diets. What began as a personal test widens into a broader reflection on the future of food, as momentum builds around a changing food industry and the choices that may redefine how we eat.

A chilling investigation dives into the looming threat scientists call “Disease X” — an unknown pathogen capable of triggering the next global pandemic. Led by physician and broadcaster Chris van Tulleken, the documentary explores how modern life, global travel, and human–animal contact are creating the perfect conditions for a catastrophic outbreak. What begins as a scientific inquiry quickly becomes a race against time to understand how close we may already be to the next crisis.
To uncover where Disease X might emerge, van Tulleken retraces the fault lines of past outbreaks, from the deadly Nipah virus in Malaysia to the spread of bird flu among dairy cattle in California. Through frontline reporting, expert interviews, and unsettling real-world examples, the film reveals how fragile global health defenses truly are — and why the next pandemic may not be a question of if, but when.

In this powerful continuation of his personal journey, Chris Hemsworth takes viewers around the world to test the boundaries of body and mind. Confronted with chronic back pain and concerns about memory decline, he seeks answers not in laboratories but in life-changing challenges designed by scientists, health experts, and elite trainers. From the nerve-racking task of learning to play the drums—culminating in a breathtaking live performance with Ed Sheeran before 70,000 fans—to enduring brutal Special Forces–style trials in South Korea involving electrocution, pepper spray, and freezing waters, each step reveals the fragile balance between vulnerability and resilience. His raw honesty and willingness to fail make the journey as intimate as it is inspiring.
On our website, viewers can enjoy the entire adventure with the three episodes combined into a single video, seamlessly following Hemsworth as he explores how to live better, face fear, and unlock the science of resilience and longevity.
