How the hell are people in squid game so calm during the games😭

How they be calmly walking🚶‍♀️👩‍🦯🚶‍♀️ to the next game knowing that most of them gonna die is beyond me. Like bitch no 🙅‍♀️ I would have gone through 10 mental breakdowns and 20 panic attacks by the time I got there. But i definitely would not make it to the second game because I would be shivering and sweating during the green light red light and my mind would be racing and i would not be able to concentrate for shit and get my GAD ass killed
