Siberian hermit

Agafia, who was born on the reclusive homestead, had not seen anything of modern life except the debris of Russian rockets that fell, and still remain, near their cabin. Until their discovery in 1978 by a team doing an aerial geological survey, the Lykovs hadn't seen other humans for 40 years.
The 70-year-old woman, who has spent her entire life in the wilderness, called for help with an emergency satellite phone.
