...there is no good culture without people trying something new...
otherwise, that is heritage
My thinking is that a people cannot preserve their exact lifestyle without taking away from their culture. A tradition is a custom that continues from generation and regenerates with the coming generation. But a culture that locks its place in stone is inheriting a tradition of frozenness; a trait that alters their original intention of preserving their culture.
Man changes each day. A culture that denies changes moves from its base of nature and shifts away from natures natural process of change.. Perhaps like a stone sliding.. sliding over a cliff slowly and slowly and then falls in when it no longer has any base in reality.
