A 50-year-old Spanish extreme athlete spent 500 days at a depth of 70 meters without any contact with the outside world as part of an experiment that will now be studied by scientists from various fields.
This is stated in the Reuters publication.
Beatrice Flamini was 48 years old when she descended into a cave near Granada. A woman celebrated two birthdays alone underground. Her stay was closely monitored by scientists who sought to learn more about the capabilities of the human mind and circadian rhythms.
The woman began her experiment on Saturday, November 20, 2021, before the full-scale war in Ukraine, Spain's repeal of its long-standing requirement to wear masks against the coronavirus and the death of Britain's Queen Elizabeth II.
On Friday, April 14, 2023, she was born in the south of Spain wearing dark glasses.
