Imho, I think the reason why we become negative around the computer is because, as much as well all hate to admit it, we are animals. It is unnatural for a human being to be sitting in the exact same spot for 8 or so hours a day. Humans are meant to hunt, gather, farm, or do some other activity that at least involves walking or making something. We are meant to do something that involves more than moving our fingers for 8 hours. Because of our self imposed constraints to "do a good job" as part of the corporate/gov't workforce, we force ourself, against our natures, to be tied down to a desk all day and only move our fingers.

Now, the reason, I believe, the waterfall and other aspects of nature create a calming affect is simply because we are animals. The natural surroundings appeal to our instictual animal self. Humans are rather unique in being a wanderers and we also are rather unique in liking "pretty" things. Most waterfalls are pretty. Flowers, the way the light falls through the autumn leaves, these are the things we enjoy because almost all humans enjoy natural aspects of life given our feral past.
