I'm vegetarian, I'm not dead at least.

People are meant to eat meat, but only in small amounts, and meat like chicken and fish is much better for you than red meat. If you're vegetarian you can get all the nutrients you need from other foods, but you aren't necessarily healthier (although you are definitely healthier than people who can't imagine eating without a big greasy lump of meat involved, and whose vegetable intake consists of potatoes and bugger all else.)
