It depends on their age. In Seoul it's not uncommon to see men under 35 who are that tall. It's not the majority but I wouldn't look twice at a man that tall because they are around.
It all depends when someone was born and their childhood nutrition. Someone growing up poor in a rural area in the 1960s won't be as tall as someone who was born to an upper middle class family in Seoul in 1980.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
