Here are the 100 weirdest and most interesting facts about the human body.

56. The average ashes from a person's cremation weigh about 9 pounds.

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 shrinks, causing the sensation that the nail plates and hair are enlarged.

58. By the time they reach their 60th birthday, most people have lost about half of their taste buds.

You should not find fault with your grandmother with claims that she has become worse at cooking. Older people tend to lose the ability to taste and make dishes with much more intense flavors because they find it normal. Therefore we only in youth, are 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 its big eyes, it is worth understanding that they will be the same size throughout his life. Their ears and nose, however, will continue to grow.

Most of us get injured and get sick at some point in our lives. Here are some interesting facts about how the human body reacts to stress and danger in the outside world.

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

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

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

Provided there is water, the average person can live up to two months without food, depending on the amount of body fat and other factors. But if a person is deprived of sleep, then he begins to experience radical psychological changes in personality after just 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 original state. normal condition. Note that the next time you feel too lazy to apply sunscreen, remember this fact before heading outside.

High levels of stress (for example, at work) can increase the chances of having a baby. serious illnesses like depression, high blood pressure and heart disease.

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

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

If you're trying to give your face a little workout, smile, it's 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 in the skull. This is necessary 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 compared to the evening.

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