The leader nervously reminded, "Later, when you hear a swoosh sound, remember to lower your head, or else you'll lose your life."
Rosen, puzzled, asked, "What do you mean by that? I understand what you mean by getting a haircut. It's just a haircut; it won't cost a life."
"No, if I hadn't ducked my head just now, my head would have been moving elsewhere," the leader explained. "At that critical moment, I quickly lowered my head in a matter of milliseconds to dodge that blade; otherwise, I'd be dead."
Upon hearing this, Rosen's face turned pale: "How is it possible that you managed to duck in a matter of milliseconds? That's impossible."
"I should mention, it's because I usually look at my phone, becoming one of the 'head-down tribe.' My ability to lower my head is unexpectedly good. I leveraged this ability to quickly duck just now and avoid getting killed."
"Hell, what do I do then? I'm not part of the head-down tribe and have no talent for ducking my head."
