Thanx for your repy QA,i guess what is crude is when biased and conditioned and almost thinkin were an invincible society like us invade these poor untouched innocent and real civilisation, of the amazon who are the elite in the high pecking order of humanity as they dont bother any one but are in tune with nature.We may have so called evolved and are still suffering in an advanced world but yet these people are continuing what there predecessors have done, it must work for them as they continue to to do so as they have for many centuries....true they can go for a walk in the the forresst if they were to so have a "condition", but i see a shrink who gives me synthetic drugs and i go for a walk in the maze of a concrete jungle instead.....!!!!
