Man who walked 50,000 km across 4 continents over 28 years returns home

British adventurer Karl Bushby, who set out from Chile in 1998 at the age of 29, has returned home after walking 50,000 km across four continents over 28 years without using motorised transport. The 57-year-old faced visa troubles and even spent time in jail in Panama for entering Panama without visa. Around 500 people welcomed him in England's Hull.
