Cave explorer Andrew Eavis
The British cave explorer Andrew Eavis is said to have discovered more territory on earth than anyone else alive - all of it underground. Now in his sixties, he's just spent a month in Borneo exploring one of the world's biggest underground chambers - it's all part of his continuing efforts to map caves around the globe.
