this documentary by marian cooper be absolutely amazing . i saw it tonight on turner classic movie channel . i think i will see if i can order a copy of it on dvd . the film footage doesn not look all blurry and choppy like you might think from 1925 b and w silent film . set in iran in 1925 and the nomadic tribe people in the documentary leave their desert home and cross a raging river and men and woman and child and animal . then up and over a snowy mountain pas all barefoot . it be sink or swim and climb or die . in search of grass for their animal . they have cow and goat and dog and horse and mule . in one scene a man be carry a mule who be too sick to climb the mountain . the child in the documentary all look happy and healthy . they have such a hard life . i wonder if the nomadic tribe of iran still live like this . make you appreciate modern life in usa .
