I agree with you on that.
But i did find a seemingly interesting video on youtube, but guess what..., its in another language...spanish i think.
Too bad... i would like to hear it in english.
I trier to find it to show you... but can't find it anymore. Sorry.
But i did find a small segment of that "spanish" video from the smithsonian channel, here it is...
I also had found these awhile back... enjoy!
Take care
