When I go near a hill or dune, I feel desire to climb there and have a wider look on the surroundings. I know a lot of people who love mountains and want to climb higher and higher, but never have thought about why... Many people climb high building, restaurants on TV towers are very expensive, but very popular anyway.

I've recently started to think about it. From evolutionary point of view taking higher ground have made a lot of sense. Predators could be seen from larger distance, and in the era of fighting communities, higher grounds such as hills were higher to conquer.

But is such theory scientifically proven? Are there actually any researches on why people want actually to climb higher?
