There is also an incredible documentary on cuba i watched on how everyone trades there, and like.. the ancestry coulture, and how mechanics's sons are mechanics and their sons become that as well and so on and so forth, but how its like that FOR EVERY trade... so like every trade has a dominant family that does each trade and so on and so forth, and how the reason all the old cars look new over there, is cause they have just mastered working on 50's cars, to the point of being able to reproduce panaling and engines and etc.. its all very cool
