Was she always like this, and getting that pissed stressed her heart, or was she irrational from some health problem that then finished her off? I had a relative with heart problems who had a widowmaker while out in a field getting mad at a stuck tractor. He had been told "you gotta stop taking that tractor out there. it always gets stuck and then you get really mad and you're going to have a heart attack." At least it happened fast, I guess.
So, did she die like she lived (angry, violent), like he did, or is it sadder?
