I specifically mentioned that analogy was not accurate. I have to add that it's the kind of feeling that directly reflects teenager's physical growth, taller, quicker, faster, stronger, etc. Perhaps my original analogy led you to relate to the emotional side more. Especially in western societies, that can turn to more physical impact. Teenagers in China actually have that kind of things as well, but there is simply less room for them.

Another thing is, in a world with several nuclear weapon equipped states, can two such nations simply confront with each other? Look around east Asia, you have to play very carefully.

So I guess there should have been more context to put in to have a better idea of what I was trying to deliver. If some big and vague words can explain, yeah, it's cultural difference, too.
