Haha.
My sister was a vegetarian for awhile. She believed they put hormones in cows that made girls have big boobs or something crazy like that. Well, it's not totally crazy, there is evidence that supports it, but it's a strange reason to not eat meat...
Anyway, her diet was severely lacking in a few things, and she said she was getting these huge bruises on her body, most notably on her butt just from sitting down! Needless to say, she started adding meat portions to her diet.
