You laugh when religion tells you that too much of materialistic pleasures is bad. You think fasting is ridiculous or - at the best - hypocritic. But when your dietologist tells you to stop eating too much meat, you obey with no questions asked. I guess it all depends on WHO tells you (capital letters are for emphasis, not the World Health Organization - no one hears them except for the governments) what is right and what is wrong after all...
