In action movies, we see scenes where actors dodge bullets very easily thanks to special effects. So in real life, with our reflexes, can we dodge bullets flying at extremely high speeds?
Reflex is a reaction of the body "responding" to stimuli from the internal or external environment through the nervous system; it is the basis of the nervous system's operation, helping the body always adapt to changes in living conditions of the surrounding environment.
Some of the reflexes that people often encounter in life include: when the hand touches a hot object, it is pulled back; when food is put into the mouth, the salivary glands secrete saliva;...

According to research results of scientists, the highest reflex speed of human is 120m/s. So with this reflex speed, can human "win" the speed of a flying bullet?
Renowned effects experts Jamie and Adam conducted an experiment to find the answer, but to be safe they replaced real bullets with paper bullets.
Previously, Jamie and Adam conducted a test in a closed room and achieved very positive results because they could see the light before the bullet flew out.
In ideal conditions, yes, but when they did it outdoors, the results were not as expected. Initially, Jamie and Adam tested at a distance of 183m, with Jamie trying to avoid the paper bullet that Adam fired. Jamie failed to avoid the bullet. Next, they tested at a longer distance of 365m, but the results were the same.
Then Adam and Jamie decided to switch places, but Adam couldn't avoid the bullet either. The reason is that in reality, the light before the bullet is fired is very small and is reduced in intensity by natural light.
Finally, they positioned themselves so that Jamie could see the light before the bullet flew out most clearly and extended the distance to more than 457m. This time, Jamie dodged the bullet perfectly.
In short : In real life, it is impossible for a human to avoid a flying bullet!
