Our neighbours are anthropologists. They spend several months a year with a small tribe in the jungle in South America. They're 7 hours

When they come back & show us photos of the way they live, lots of people are horrified. But that's just it- they live. They use common sense & come back fighting fit. No fridges- no freezers, but they survive. The tribe they live with always look a damn sight fitter than the people on my local high street too.
