I've met a few people that just don't like meat and never have. I almost wonder if it is because their bodies know that they don't tolerate it well.
I tolerate it well, it's that I have always been kind of grossed out by it. Maybe because I knew it was a dead animal and looking at the bones and the veins turned me off. And that goes for beef, chicken, and fish. It's funny because I won't eat soy burgers or anything else that pretends to meat. Just really hate the taste and texture, I guess.
