Yeah, reminded me of an archaeology professor I once had (before I dropped out), who told a story about him visiting a remote African village, somewhere in Central Africa.
He was staying with this tribe in tiny village. No technology, no modern things whatsoever (mind you, this is probably 20-30 years ago). He would wonder why the tribesmen took so little notice of the airplanes that often flew over the village, and asked them, what they believed it was.
"Oh, those are just the iron dragons", they replied (according to him, anyways).
A few days later a man from the neighbor village came along. He had an ox (or some beast) dragging his cart. This was of great amusement to the folks in the tribe; apparently they had never seen anyone putting an animal and a cart together, and found it laughable, even ridiculous.
I'm not sure how credible this story is, but it comes from an esteemed professor (...), and I guess it goes to show how cultural constructs can (and do) affect our lives.
Even if it is a fake story, it is great example still. It is fascinating how we think that we do it all right, but never even thought that we could do everything else completely different!
Yes. We are all susceptible to that, whether we think it or not...
