A tragic story of going off the grid Robinson Crusoe-style in response to the horrors of war, via the BBC:
A Vietnamese father and his son who fled to the jungle during the Vietnam War four decades ago have been persuaded to leave, officials say. Ho Van Lang and his 82-year-old father fled to the jungle after being traumatised when three family members were killed by a landmine.
For most of their time in the jungle their whereabouts was unknown. They were discovered living in dense foliage in central Quang Ngai province and were barely able to communicate.
While in the jungle, the pair wore only loincloths and used a homemade axe to chop down trees. They survived on corn, fruits and cassava roots from the jungle. They lived in a tree house, five metres above ground, where they kept arrows for hunting and knives for killing animals.
The older man kept his military trousers neatly folded in a corner as well as the little red coat his son was thought to have been wearing when they fled.
