because it doesn't benefit me. now if we're talking about the videos of China youth fashion style then we can personally benefit from that we can copy their style to improve ourselves etc.

if someone says you're short counteracting that with a study showing China youths are tall doesn't help you, youre still short. if a girl doesn't want to date you because she thinks you're short, telling her guys in Beijing are tall won't help you, it just means you're shorter than whites blacks and even guys in China. it actually lowers your status in her eyes even more.

basketball is the number 1 team sport related to height dominated by USA, thats why mentioned it, since height is the topic. of course China beats USA at many other sports but those sports aren't about a national team of alltall guys vs another national team of all tall guys.
