urg. i just searched it up. why would you willingly want to pass out? your blood is not getting enough oxygen, and so your body cannot get enough nutrients. if the brain does not have enough oxygenized blood in a surprisingly small amount of time, [like 30-40 seconds] you will pass out, and sometimes your windpipe could get blocked, so you have even less oxygen. you will then die if the windpipe is not relieved. where did people even think of this challenge? more proof for why tik tok is slowly sending this generation into certain doom.
