The human body is an incredibly complex and confusing system that still baffles doctors and scientists on a regular basis, despite thousands of years of medical knowledge. As a result, there should be no surprise that even the parts of the body and functions that we deal with every day are fraught with strange and unexpected facts and explanations. Here are 100 of the weirdest and most interesting facts about the human body.

56. The ashes of a cremated person weigh about 9 pounds on average.

Much of what gives weight to the human body is water, which is trapped in our cells. After cremation, most of our tissues are destroyed and the water evaporates.

57. Nails and hair do not continue to grow after death.

They become larger after death, but this happens only due to the fact that the skin dehydrates and decreases, causing against this background the feeling that the nail plates and hair are increasing.

58. By the age of 60, most people have lost about half of their taste buds.

You should not find fault with your grandmother with claims that she began to cook worse. Older people tend to lose the ability to taste, and make dishes with a much more intense taste, as it seems normal to them. That's why we only in youth able to appreciate the real taste.

59. Your eyes are always the same size from birth to death, and your nose and ears never stop growing.

When a baby looks at you with his big eyes, you should understand that they will be the same size throughout his life. But their ears and nose, however, will grow constantly.

60. By age 60, 60% of men and 40% of women snore.

Normal snoring, on average, is about 60 decibels, which is the noise level of normal speech, intense snoring can reach more than 80 decibels, and this is already a sound similar to what causes jackhammer destroying concrete.

61. The head of a child is one fourth of its total length, but at the age of 25 it will be only one eighth.

It turns out that the child will not change the size of his head as dramatically as the rest of his body. The legs and torso will lengthen, but the head will take much longer.

Most of us get hurt and sick at some point in our lives. Here are some Interesting Facts about how the human body reacts to the stresses and dangers of the outside world.

62. Monday is the day of the week when the risk of a heart attack is highest.

Another reason to hate Mondays! A ten-year study in Scotland found that 20% more people die of heart attacks on Mondays than on any other day of the week. The researchers suggest that this is caused by a combination of excess pleasure over the past weekend, as well as stress caused by the need to return to work, which leads to a serious increase in risk.

63. A person can go longer without food than without sleep.

Provided that there is water, the average person can live up to two months without food, depending on the amount of fat in the body and other factors. But if a person is deprived of sleep, then he begins to experience radical psychological changes in personality already after a few sleepless days. The longest (recorded) time spent by a person without sleep is 11 days, after which the experimenter did not sleep, but also could not speak clearly, experienced hallucinations and often forgot what he was doing.

64. A simple tan causes blood vessels moderate damage.

Studies have shown that it takes four to fifteen months for the vessels to return to their normal condition. Keep in mind that the next time you feel too lazy to apply sunscreen, remember this fact before heading out into the street.

65. More than 90% of diseases are caused or complicated by stress.

High levels of stress (let's say at work) can increase the chances of giving birth to a number of serious illnesses like depression, high blood pressure and heart disease.

66. human head remains conscious for approximately 15 to 20 seconds after it has been separated from the body.

As cruel as it sounds, after being "decapitated" the blood in the head can be enough to keep someone alive and conscious for a few seconds after the head has been severed from the body. Perhaps the kats guessed this, since they lifted the severed head by the hair and let it look at their body and the crowd that had gathered to watch the execution.

Interesting facts about muscles and bones

Muscles and bones are known to provide the framework for our body and allow us to jump, run, or simply lie on the couch. Here are some interesting facts to give you something to think about the next time you get bored.

67. 17 muscles are used to smile and 43 to frown.

If you're trying to give your face a little exercise, smile is the easiest option for most of us.

68. Babies are born with 300 bones, but adult life this number is reduced to 206.

The reason for this is that many of the bones of children are made up of smaller bone components that are not yet fused, as is the case in the skull. This is necessary in order to make it easier for the child to go through birth canal. Bones harden and join together over time as children grow.

69. We are about 1 cm taller in the morning than in the evening.

The cartilage between our bones shrinks when we stand, sit, or do other daily activities throughout the day, causing us to get a little shorter by the end of the day.

70. The strongest muscle in the human body is the tongue.

You should think about this fact when you eat, swallow, or speak, while constantly using the language that provides the above functions, so that he exercises quite a lot during the day.

71. Jawbone one of the strongest bones in the body.

Incredibly, it is the jawbone that is the hardest to break.

72. You use 200 muscles to take one step.

To take just one step you use somewhere in the region of 200 muscles. It's a lot of work for your muscles considering what most of us do about 10,000 steps per day.

73. Teeth cannot repair themselves.

The outer layer of tooth enamel, in fact, is not a living tissue. And since it is not alive, it cannot self-repair, so the dentist has to do this work. Although, I recently read about the invention of a drug that makes teeth regenerate, but on this moment there are few materials for the article, when something becomes clear around this invention - I will write an article about it, so stay tuned to, and in order not to miss anything, subscribe to new articles on e-mail(You will receive notifications about new articles), or better yet, join the VKontakte group, and on the widget located in the block on the right, click "Subscribe by SMS" and then you will receive free sms, with the subject new article after its publication.
