I've been a vegetarian for about 20 years now. I was a vegie from birth until about 2 years old, then ate meat until I was about four, then went back to being a vegie when I was force fed Liver and Onion at my parents hotel.

I don't think there is any real social pressure on me to eat meat. Once in a while I get a jerk who isn't one of my friends trying to explain to me the "error of my ways". But it's pretty easy to shrug that off, with an equally obscene response of something like "animals are my friends, and you don't eat your friends do you?". Ha.

But the real reason is I can get by fine without eating meat and would be viciously sick I'm sure if I ever attempted to eat meat now.
