i thought we were talking about how some religions restrict on food though this is going elsewhere also but in reply to that, can check this out (controversial though and sorry for that...i still got to see the documentary as been curious about it): the documentary was released late last year and done by an australian.
http://www.imdb.com/title/tt1857666/ - Decadence: Decline of the Western World (7 out of 10): It explores the rise of porn, the demise of egalitarianism and the spread of junk culture. It examines the neutering of democracy and the unstoppable growth of mercantilism. It touches on the collapse of faith and the fracturing of families. All civilisations rise and fall. For 300 years, the Judeo-Christian West has been the world's pre-eminent civilisation. So, where is the West on the timeline? Many have theorised about the fall of the western world but now we appear to have the evidence. Negative birth rates, ageing populations, debt-laden economies and immigration - the West consumes without consequence, loves without longevity and lives without meaning. Decadence, a simple powerful essay-style documentary, asks if the West has peaked? And due for a new renaissance or a final dark age?
