What are the odds of dying of old age, at home, asleep in bed?

I was wondering what the odds were that the average person will die of old age, at home in their sleep? Is it logical to conclude with the advances in medicine, fewer people are dying of disease, and more from accidental injury than in the past? And with heroic medical intervention, it seems like it is very likely most people will die in hospitals, either fighting a disease or traumatic injury.

Anybody know the statistics on this?
