We will all die (I am still not sure about XX Gong leader). So if one group of people, say S Korean
has lower death rate due to lung cancer than
American, then S Korean must have a higher
rate of death due to another disease
or a unnatual cause.
But I seldom see any medical research papers
compare mortality rate within a age frame
say, below 80. So it does not make any sense
to me.
