Yossi Ghinsberg set out with three friends in 1981 to explore the Tuichi River in the Bolivian Amazon. Lost and realizing that they hadn't prepared well for the arduous journey, they broke off into pairs. Ghinsberg and his friend Kevin floated on a raft down river. The other pair was not as fortunate: They were never seen again.
Unfortunately, Ghinsberg's raft hit a rock, and the pair were split up. Ghinsberg spent the next 19 days wandering alone through the wilderness. Local men found Kevin, and they began a search for Ghinsberg. Miraculously, he was found alive. Ghinsberg is now a motivational speaker who inspires audiences with his tale of survival.
