31-year-old Spencer West, of Toronto, Canada, lost his legs at five-years-old and was told by doctors that he would never be able to sit up, let alone walk. However, through sheer willpower he proved them wrong and did the seemingly impossible: he climbed Mt. Kilimanjaro over a grueling seven-day period. Traveling on his hands for 80% of the trek, West was able to achieve his goal with his two good friends by his side. He spent an entire year training for the climb to ensure his arms were strong enough to handle the trip. In addition, his incredible achievement helped raise £300,000 for the educational charity Free the Children.
