Two high school boys named Randy Gardner and Bruce McAllister wanted to record the brain’s responses when the body was severely sleep deprived. Later, looking back at the old experiment, both Randy Gardner and Bruce McAllister felt that they were too reckless and foolish to risk their health for an experiment that they themselves did not fully anticipate the possible risk. happen.

At that time, two teenagers toss a coin and Randy Gardner is the one who has to perform the experiment. Meanwhile, Bruce McAllister was also at first awake with you to watch and cheer you on. But after three days without sleep, Bruce couldn’t stand it. Accompanying two teenagers in this experiment are scientists specializing in human sleep research.

Finally, Gardner broke the previous record, the teenager stayed awake for 264 hours without sleep (equivalent to 11 days). After taking on the challenge, Gardner experienced changes in his emotional state, suffered short-term memory loss, and experienced some concentration problems. In addition, he experienced symptoms of hallucinations and paranoia.

When taking on the challenge, Robert McDonald was 27 years old and a stuntman. After completing the challenge, McDonald once shared with the US media: “This is not an easy experience at all. I always feel like I’m going to faint, I constantly have the feeling of vomiting and waking up. Eat like you want to reflux out.”

After completing the challenge, Robert had periods of weight loss and found it difficult to remember information. During his stunt career, Robert McDonald has performed many dangerous stunts, but this man still considers performing the sleepless challenge to establish a Guinness World Record as the most dangerous thing. i used to do.
