A sportswoman named Beatriz Flamini has today emerged from a cave in the province of Granada, Spain, where she voluntarily isolated herself 70 metres deep for 500 days, without any contact with the outside world. This is a self-improvement project that was followed by a documentary production team. The initiative involves researchers in experimental psychology and behavioural physiology from the University of Granada, in clinical neuropsychology from the University of Almería, as well as from Kronohealth, a spin-off company of the University of Murcia's Chronobiology laboratory.
