Saroo Brierly was separated from his family when he was just 5 years old. He'd gotten on a train, fallen asleep and woken up in Calcutta, far away from his hometown -- a home he didn't even know the name of. He was eventually adopted by an Australian couple but recently used Google Earth to research where he might be from. He reunited with his mom 25 years after being separated from her.
