Why do boys generally become more handsome and temperament after a period of fitness?
Because men have been good hunters and athletes since ancient times, they have adventurous spirit and courage, but modern society is under great pressure and has no time to exercise, so they gradually become less strong, so after a period of fitness, they have recovered their original strong physique. Men are handsome and have temperament, but this side of men has been abandoned by the times, so they will appear decadent and have no temperament.
