Many things about humans are taken for granted, one of which is our fingerprints. But surprisingly, not all of them formed fingerprints, which makes their lives a bit difficult. Therefore, it is natural that we ask ourselves how it is possible and that we ask scientists for an explanation.
Unfortunately, for some things in life, science only has assumptions to give us rather than clear answers. We want to shed some light on 12 human characteristics and abilities for which we have not yet found a scientific explanation.
How Someone Can Stay Without Oxygen For 20 Minutes
According to scientists, 30-180 seconds without oxygen can make you lose consciousness. After 3 minutes, the brain begins to damage, and within 10 minutes, a coma should occur. However, there are training methods that allow the brain to survive without oxygen for long periods of time.
More specifically, Budimir Buddha Sobat broke a world record by staying underwater for 24 minutes and 33 seconds. He beat Aleix Segura’s previous record by 30 seconds. The only thing the two of them did before entering the water was breathing pure oxygen for a few minutes.
How Someone Can Stay Awake For 11 Days
In 1963, a 17-year-old boy named Randy Gardner managed to stay awake for 11 days and 25 minutes. The asleep researcher was with him the entire time monitoring how his cognitive abilities were affected.
The boy was still active playing basketball, while the people around him made sure he didn’t fall asleep. During the 11 days, his sense of smell and taste was severely affected.
And the reason for this is probably because the term “agreed” is not specific. Someone may have their eyes open, but the brain may be completely off.
The Number Of Days A Person Can Go Without Water
The general rule of thumb is that humans can go without water for up to 3 days. However, this depends on several factors, such as age, physical activity, and general health. Also, if your diet consists of a lot of watery foods, such as fruits and vegetables, your water sources increase.
In 1979, a man named Andreas Mihavecz survived without water for 18 days in a row. He was kept in a police cell and the guards responsible completely forgot about him.
The way he managed to stay hydrated was by licking the condensation off the walls of his cell. This is really spectacular when you think about the fact that he wasn’t getting food either.
Why We Need Our Appendix
The appendix is one of the organs that is often removed from the human body. This is one of the reasons why many scientists used to believe that it was useless.
However, according to biologist Heather Smith, 533 species of mammals have an appendix, a fact that proves their importance. More specifically, an appendix protects our immune system.
The way it works is by harboring many “good” microbes that the body uses when it is affected by disease. However, there is no evidence that those who removed the appendix are more susceptible to the disease.
Therefore, the end result is that we have some knowledge of the use of the appendix in our body. But more detailed studies are needed to understand the complexity of the organ.
Why We Have Dominant Hands
About 85% of humans are born with the dominant right hand. One theory for this occurrence is that the left hemisphere of our brain controls our speech and movement abilities.
It also controls the movement of our right hand, which makes us right-handed. Another theory says that being right-handed dates back to the first humans on Earth and the use of tools.
Until 2 million years ago, humans were predominantly right-handed, which is why all of their tools were created to accommodate this trend.
It is said that there was a small percentage of left-handers and that they would have had an advantage in combat. If your enemy expects you to hit them with your right hand, but you hit him with your left, you are more likely to win.
Which of the above events surprised you the most? Wouldn’t it be surprising if men had developed their breasts too?
