In 1954, when none of the present-day facilities were available to travelers, my brother and I embarked on a perilous ten-year-long journey across the world. Enduring great hardships, we traveled to the most breathtaking places across the five continents. Crossing the Arctic Circle, we spent three years traveling from the northernmost point of Canada to the Tierra del Fuego, at the southern tip of the American continent, spending every moment of our lives looking, thinking and gathering experience, mostly about the indigenous peoples who first reached the American continent.
