Had to laugh at Stanley Johnson when he asked Vardys missus that as an England player would Jamie play in the Ashes.! Can't remember which paper I read it in, but a lot of what happens is " stage managed." They are only about a mile from " civilisation" and the base housing Ant and Dec and the film crew. It is all inter linked with ramps and walkways so if needed medics can get in quickly. When it rains the contestants don't get wet and the fire doesn't go out because there is a canopy 50 feet above them in the trees. The kindling for the fire is chopped and scattered around the immediate area, so all the camp mates have to do is gather it up. The waterfall that they can bathe under is turned off at certain times of the day to conserve water and whilst they are not allowed extra food the campmates are allowed luxuries like pillows/ cushions and any smokers receive regular supplies of cigarettes.
