Given how sustainability is and undoubtedly will remain the ultimate buzzword between now and the end of life on earth, two friends of mine decided to tackle it head-on, by relocating and making some radical changes to how they live.
Three years ago, the couple — a yoga teacher and a builder — bought a few acres of arid hillside deep in rural southern Portugal, for the kind of money that might buy you a parking space in the Dublin suburbs.
This idea was not like those TV shows where retirees buy a holiday home in a gated community around a blue tiled pool somewhere Mediterranean.
No. Their hillside is miles from the nearest village and a steep drive on a dirt track that without a map is impossible to find.
