The self-sufficient approach taken by the record-breaking mountaineering couple

Nives Meroi and Romano Benet from Italy became the first married couple to scale all the eight-thousanders - the 14 highest mountains on earth - and did it without using bottled oxygen. They explain their self-sufficient approach and how they got the bug: "It's like eating cherries - once you start, you can't stop."
