I am a psychology and biology major--I plan on going into neuroscience. But given the direction that this discussion has turned towards, does anyone know what it takes to become an adventurer? Before I die I would like to climb a few peaks over 20K feet (especially Everest, but I'll clearly have to work my way up. pun intended), and also visit the rain forests before they're gone, circumnavigate the globe, and visit the poles. What does it take to get funding for such excursions, or what would you speculate is needed, materially etc., in order to accomplish this?
