Sorry if this rubs some wrongly, but this old fact just popped into my mind during this thread. = The first anthropologists to make "friends" with Pigmy people of the deep Amazon jungle, convinced some tribesmen to accompany the scientists out of the dense forests for the first time ever. Standing together, looking out over the wide open plain, all the pigmies started pointing and "giggling". What they were laughing at was seeing far off, some field working people who were way smaller than the pygmies themselves. You see, they had never used or developed any "distant-vision" and they thought those people were actually that small. (True story.) :cool:
