I was flipping through a Year Book Encyclopedia from 1972 when I found an intriguing picture of a thin Japanese man crying in a wheel chair. The man was Yokoi Shoichi, a Japanese soldier form WWII who hid in the jungle in Guam rather than surrender, and stayed there for 28 years. My favorite part about the encyclopedia story (that's not in the Wikipedia one) is that he told reporters, "I'd like to be reunited with my family and then go up on a mountain and meditate for a long time."
