These age rules are indeed different; all designed to benefit beefy slabs of meat type. Like wise rule changes in field hockey, badminton, etc are all done to benefit the occident ( with the flimsy reasons that they are needed to capture more spectators and new equipments like astroturf, etc ). All the talk of fair play and crowing in the " mass media ' about openness and transparency are ways to hypnotically hoodwink the self righteous believers of so called " freedom ". Fellas, you ain't free.......you just think you are free with the constant bombardment of CNN, BBC, other " freeworld " mass media which have subliminally captured your subconscious.
Of course the communist and other dictatorial regimes like China, North Korea etc uses the media as propaganda tools........we all know that, so we are wary of their official pronouncements. As for the so called " free " western press, the perception that they aree " free " LULL the general public to accept wholesale what is dished out, subliminally accepting the hidden agenda of the powerful so called " industrial-military-pharma " interests which are the real shadowy power behind geopilitical upheavals.
