ABSTRACT
A nightmare Imagine you wake up and find yourself not in your bed or even in your own home, but in the middle of a jungle. You are in an unfamiliar and hostile environment. There are no roads, no buildings, no signs whatsoever of human civilisation. And it gets worse. You have no means to communicate: no mobile phone or laptop; you have no food or drink and just the clothes on your back. You really are in trouble! You are back in the Stone Age.
