3. What experiment did Michel Siffre
conduct? What was its outcome?
From the science journalism of the most forgetful man in the world from moonwalking with Einstein

Michel Sifre was a French chronobiologist who studied the relationship between time and living organisms. He conducted a self-experimentation in 1962.

In his experimentation, he spent two months living in total isolation in a cave - had no acess to calendar, clock or even sun. In a short while, his memory deteriorated since there was no one to talk to, no book to read to impress itself upon his memory. It got to a point, he stopped being able to remember what took place a day before. As the days went by, Sifre became effectively amnesic, he could not sleep very - he would stay awake for thirty-six straight hours in some days. The outcome of his self-experimentation was severe.

By the time his experimentation was to wrap up in September 14, it was only August 20 in his journal. He only thought a month has just passed.
