Mike Horn
(Mike Horn is largely considered to be the greatest modern explorer. He has completed journeys around the equator as well as the Arctic Circle — both without motorised transport. He has walked across Siberia for one and a half years — alone. And when he teamed up with Norwegian explorer Borge Ousland, they became the first men to travel without dogs or motor to the North Pole during the permanent darkness of Arctic winter. These are just some of his feats. His greatest achievement is perhaps pushing beyond the boundaries of human ability and imagination, and managing to stay alive. Horn was engaged as a motivational speaker for the Indian cricket team during their 2011 World Cup campaign. He has also worked with the Mumbai Indians.)
