Bacon Sandwiches.

Food  Not something for vegetarians, I should warn you, but this interview with a butcher about how the emotional state of a pig effects the bacon's quality is fascinating:

"Not only does pork have a remarkable ability to absorb the odours around it – far more than any other meat – but it is also affected by the pig's health and happiness, right up to the time of death. A pig that has been stressed in its final hours – by being separated from its family group, say, and transported many miles to be slaughtered – will have a noticeable toughness, bruising or even a sewage-like taint. Buttercross's pigs travel a mere three miles to their final demise."

I wonder if that's true of all animals.
