[B2] In this episode, I’ll tell you the true and fascinating story of Michel Siffre — a French scientist who, in 1972, chose to live underground for six months, in complete darkness, with no sunlight, no clock, and no human contact.

An extreme experiment to understand how our brain perceives time when it loses all external references. What happens to our mind when we have no idea what time it is? And how long can we endure isolation?

We’ll talk about:

– How the brain creates its own sense of time

– The psychological risks of extreme solitude

– Siffre’s biological rhythm: 36 hours awake, 12 hours asleep

– The emotional and mental consequences of the experiment

– The scientific discoveries that came from his sacrifice

At the end, I’ll ask you some big questions:

Could you survive in such conditions? What is time, really? Is it real… or is it just a creation of our mind?

🧠 A powerful story, perfect for practicing your Italian… and for thinking deeply.
