It is not known unexpectedly, but even a healthy person may die suddenly.
It is a heart attack.
The heart attack can happen to anyone.
Though there was not abnormality, the example passed away cannot know the number for a heart attack by a medical examination overnight.
I think, but と which "is such a fool" is a real subject.
Is the example that a healthy person died of a sudden heart attack reported how many?
It may take place in not only old people but also the young people.
"Why did you suffer from a heart attack? The case regretted, it was such healthy exists all over the world.
I do not know when we human being dies when I think some other time.
The possibility may be less than 1%, but is not 0%.
It is an imprudent talk, but is a story to be possible as a fact.
