There is a tremendous amount of romanticism which surrounds going off on expeditions to remote parts of the world and camping in tents, and living in a desert and struggling with all of the trials and tribulations that one encounters. But, I think that what really intrigued me was the fact that I felt that this was and still is really, a science, a form of inquiry, which is still in its infancy. That there were so many things yet to be discovered, that the science itself would have, in my lifetime, still lots of surprises.
