People end up lost or missing for a number of reasons, but it usually boils down to either kidnapping, death or because they wanted to get lost.
Anton Pilipa was declared missing by his family when he seemingly vanished in 2012, but he wasn't kidnapped and he certainly isn't dead- he just decided to take a walk from Vancouver to The National Library of Buenos Aires.
His family feared the worst because Anton is schizophrenic, but Anton made it all the way to the National Library in Buenos Aires on foot- where he was sent away because he had no ID.
Then Anton walked barefoot to Brazil and lived in the Amazon rainforest for years, where he was taken into custody by a Canadian-born Brazilian policewoman who initially thought he was a beggar.
She was able to work with a few international agencies and embassies and track down Anton's family, who flew down to bring him home.
He described how he survived by picking fruits and berries, scrounging for food and clothes in the trash, and relying on the generosity of strangers.
But that’s not to say times weren’t tough. Anton started off with a small bag of belongings but was robbed of what little he did have on several occasions.
While walking 800km alone through the dangerous Amazon jungle, filled with poisonous spiders, snakes, caiman – which can grow up to 6m long – and jaguar, all his toenails dropped off.
Yet, while he met some "bad people" on his incredible 10,000 mile journey, he said he had "received more generosity, especially in recent times."
"I've never felt alone,' he said. "It's been a lot of thinking for years, sleeping in the open. It's very simple to live, we do not need many things."
