I stayed for a night with a friend who is a vegetarian among colleagues. In the evening, we ate the fruit and vegetables (separately). As a result, most of the vegetables were in my plate. On the question, and why then she was recorded at herbivore work, she shared that she doesn't like to cut meat - to say, slippery, unpleasant to mess. So the secret of where vegetarians come from is simple – they become those who have not been able to overcome lazyness...well or especially lazy creatures.
