I took to eating some chicken and fish. I know I could not kill a chicken, or a fish for that matter. Though I am happy to rip a carrot out of the ground. What's that carrot ever done to me, idk but I'm going to munch it's little heart out.
I think there's a bit of a thing with young teenage girls, something changes, it certainly happened to me - I went from not bothered to repulsed by the smell at the butchers.
Interesting considering that is the age when the need for iron increases.
