"Time is your biggest enemy but it's also your greatest advantage because it gives you time to think", says world's only double amputee, who climbed the Everest, Mark Inglis. Inglis lost legs at the age of 23 and since then he tried different occupations, but mountaineering was his true calling. He made his own climbing prosthetic legs, skiing legs and cycling legs. He now raises money through his climbing and helps people who need artificial limbs in Tibet. Inglis also helps people affected in earthquake in Nepal last year. Mark says, "I'm always breaking things, but at least when I break a leg, it only takes me a few hours to fix it".
