An aneurysm will drop you like a sack of potatoes.
that's what I was thinking.
My father had one that eventually had to be repaired.
I have one that we measure every 6 months.
I had a cat that died of an aneurysm (at least that was the vet’s theory). I was in the kitchen making a sandwich when I heard her collar clink against her water bowl. I turned around and she was laying there, limp. It was like someone had flipped a switch.
What I don’t get is how a heart attack or aneurysm can kill so suddenly. It seems like there would be enough reserve oxygen in the blood to keep you conscious for at least a few tens of seconds. It seems strange that it can have such a sudden effect.
