I am also growing. It used to be fluff. Later, I began to exercise, and more than a year passed. One day, when I looked in the mirror, I suddenly found that my back turned into conspicuous black hair. It grows to the bottom of the spine and scapula. It looks good. Handsome, I don't care. What's wrong? Long hair shows that I have done a good job in fitness and my androgen is strong. As the old saying goes, a good man is hairy and a good woman is fat. People in the past didn't know what hormones were and what body hormones were. They only know that men with gross weight and strong women have the healthiest children. This comes from life and is the best proof. So what do you think of long hair?
