During high-school I've read an explanation for this, but unfortunately i forgot. I think heart muscle-tissue was built differently than normal muscles, but that begs the question... why are some often used muscles, like the thighs, not made the same way? Would it require too much energy or protein to sustain them? (that is of course, assuming the diet of a human living in the wild).
