Friendships are unique. Some begin in childhood and last for many years. What influence do these relationships have on the mental health of young people? How have they changed with the advent of social networks?

You may be like many others, feeling guilty about buying trainers made in China, bananas from Costa Rica or a smartphone assembled in the worst possible conditions, but without really knowing how to do things differently. Whether it's what we eat, where we live, or where the clothes we wear come from, we realise that the most basic things in our lives are beyond our control.

By discovering the work of Geneviève Pruvost, we can finally grasp the origins of this powerlessness. This sociologist and research director at EHESS also has a degree in permaculture. In her book Quotidien Politique, she has brought together little-known thoughts to understand how our daily life has escaped us. And through this perspective, she also explores how we could regain power over our living conditions.

So what really makes up everyday life? Why do we lose sight of the material basis of our existence? How can we regain power over our daily lives?

Between stress and people, it's anything but true love. According to the WHO, 85% of us would prefer to be free of this ‘disease of the 21st century’.

However, research tells us that it is not stress that makes us ill, but the way we manage it. We might even need more of it, as long as it's good stress! That would then awaken our superpowers...

For some, children are frail creatures incapable of understanding the world. For others, they are our superiors, because they have mastered things that adults have long forgotten.

Regardless of how you look at it, the differences are real. So what is the truth of the matter? Are children beings apart? And how can we understand them better?

Why do so many world maps place Europe at the centre? Why not Australia? And why is the north always at the top?

Maps may not be as neutral as you might think.

Pain has a bad reputation, and we go to great lengths to avoid it: from painkillers to general self-care. It has even been said that our society rejects not only physical pain, but social pain as well.

Religious faith is in decline in Europe, and yet 70% of human beings in the world believe in the existence of one or many deities. Do human beings need God? Are we homo religious rather than homo sapiens?

Have you ever wondered how Venice, a city built on water, became one of the most powerful and wealthy cities in history?In this episode, we uncover the extraordinary story of Venice, from its humble beginnings as a refuge for Roman citizens fleeing the Huns, to its rise as a medieval engineering marvel. Discover how the Venetians transformed a muddy lagoon into a thriving metropolis with no roads, no land, and no fresh water.

We'll explore the ingenious techniques they used to build stable foundations, construct iconic canals and bridges, and develop a unique system for fresh water and waste management.

The Eiffel Tower (/ˈaɪfəl/ EYE-fəl; French: Tour Eiffel [tuʁ ɛfɛl]) is a wrought-iron lattice tower on the Champ de Mars in Paris, France. It is named after the engineer Gustave Eiffel, whose company designed and built the tower from 1887 to 1889.

Using archive and expert interviews, this episode explores the fascinating evolution of sewers and the flush toilet.

From ancient rudimentary sewer systems dating back to 2600 BC to high-tech Japanese toilets of the digital age, the show charts the key events in the history of sewers and toilets, whilst also focussing on how modern approaches to sanitation vary across the globe.
