British adventurer details two scariest places visited during 27-year world walk

British adventurer Karl Bushby detailed two terrifying experiences during his 27-year global walk, encountering a war zone in the Darién Gap and a polar bear while crossing the Bering Strait. Bushby, who began his journey in 1998, described the Darién Gap as a dangerous area with cartels and drug plantations, while the Bering Strait crossing involved navigating ice and facing a polar bear. The 56-year-old is nearing the end of his 36,000-mile expedition and anticipates a difficult return to normal life, though he believes most of the world is good.
