The ethics of eating animals have been debated on a variety of moral levels. Until recently there was no evidence to suggest livestock animals could form emotional experiences or an awareness of their role as sustenance for human animals. Here we present high-resolution crystal structure samples of livestock brain tissue in various settings, both clinical and in situ, in vivo, at farms and processing centers, directly before slaughter. Our findings indicate the animals release large doses of the same hormones and neurotransmitters found in humans -- the so-called sex & love chemicals -- namely testosterone, oestrogen, monoamines (e.g., dopamine, serotonin & norepinephrine), oxytocin and vasopressin. We theorize livestock possess some awareness of death, and experience emotional reactions of both sexual excitement and limerence. In human emotional terms, the animals lust to die and be consumed.
