Ultramarathon runner Krasimir Georgiev takes on a new challenge. He will self-isolate in a glass cage for 15 days. The social experiment entitled “”The Glass Cage” begins today in front of the National Palace of Culture, the Sofia Municipality announced. The glass cage is a completely transparent container equipped only with a jogging machine and a bed.

A team of leading experts will closely monitor his physical and mental condition. The experiment will collect reliable data on the impact of social isolation on people’s health and the damage caused by the lack of interpersonal communication. This data will be used to create a programme aimed at reducing social isolation, easing the burden of digital technology on young people and preventing various addictions. For the purpose, a fundraising campaign will also take place.
