Is a man's height really important or not?

To ordinary people, very important. To impressive figures, it’s bullshit.
Ordinary people, you don’t have anything particularly impressive—education is average, looks are average, abilities are average, earning is average, and your penis is average.
As long as you’re ordinary, isn’t height being tall very important? At least it adds some points to your image. For ordinary people, any point that can boost your image is useful, it’s better.
For impressive figures, height is just bullshit.
In fact, the shorter, the better. When you look at Deng, is Deng tall? And even more interesting, are the people Deng promotes tall?
Moreover, during times of famine, being short has even greater advantages. Eating less, consuming less, surviving longer—if you’re 1.9 meters tall, your caloric intake is definitely more than someone who is 1.6 meters. During a famine, you’re the first to die.
Genghis Khan, Deng, Jack Ma, Napoleon, and a series of historical great figures, all were not tall. But that didn’t affect their historical status at all.
So, whether height is important or not depends on who you are. If you’re an ordinary civilian, height is very important. If you’re an impressive figure, height is bullshit.
