Well I do know a few vegetarians and two vegans but the main reason is because they dont believe in killing animals for food because they have just as much a right to be alive as we do but its however you see it really, everyone has their own opinion some people dont eat any animals apart from fish and some wont even drink milk or anything (vegan) but one thing i have NEVER seen is a overweight or even slightly fatv vegetarian, Im sure everyone has to agree with me on this one, I would say that yes you would be a lot healthier but your body also needs some of the things you get from meet especially red meet. I tried becoming a vegetarian once but its not as easy you start to miss all the foods most vegetarians started when they were small raised that way by their parent(s).
