Its was in our ancestor discovery and found the taste of new food from animal meats... it was accidentally discovered by them during the dooms day after the massive volcanos eruption, some animals were burnt to death and people curious of that tasty smell and start to eat em... and one more thing some belief by eating steamed pork with a little herb and spice will make your neurons double and expand our life to live longer. A sense of humour that lead you to have a second thought about being a vegans... I see cow get more chubby by munching only grass... :P have a fresh wheatgrass juice ... cheers
