My next door neighbour died from haemoptysis, which Viktoria mentioned earlier. He had lung cancer.
One morning I heard him coughing and coughing, then an expletive, then silence. A few minutes later his daughter ran up my back stairs telling me her dad had just died.
[Haemoptysis is coughing up of blood; haematemesis is vomiting of blood}
A friend of my OH's ran her car under a semi trailer and decapitated herself and her daughter!
One of my Blue family's DC says he 'fell down the stairs when drunk' as cause of death - didn't say buy presumably he either broke his neck or gave himself severe head injuries.
Visitation of God was usually used when they couldn't work out any other explanation, though I'm sure most people would think being struck by lightning was indeed a 'Visitation of God' !
Years ago, in Sydney, someone jumped off a moving tram and somehow fell under its wheels and horrified passengers saw his head roll into the gutter
