19. Andrei Tolstyk, Siberia, 2004
Andrei Tolstyk was born with hearing and speaking deficiencies, and this was enough for his parents to abandon him in the remote areas of Siberia, close to Lake Baikal. However, he was lucky enough to be adopted by a guard dog and was taught how to survive.
Like a guard dog, he had strong teeth, sniffed the food before eating it, he was afraid of people and generally behaved very erratically. It took him two weeks to start to walk on just two legs.
