18) Yossi Ghinsberg: Survived 3 Weeks in the Amazon Alone

Yossi Ghinsberg was just 21 when he set off to experience the Amazon in December of 1981. While traveling in Bolivia, a strange and enticing man  touted stories of adventure and lore, and promised to take Ghinsberg to the heart of the jungle. Ghinsberg was excited at the prospect and encouraged 2 new friends to come along. No one could have anticipated the ways they would be tested by nature's elements and unexpected conditions.
