New 'unbelievable' facts discovered about death

For everyone, life after death is always a mystery and no one can prove it.

Death is always one of the "hot" topics, because the surrounding is still hidden and controversial.

That might be a question about whether after death humans can feel things around for a few minutes before . shutting down? Or "the end of the tunnel" that people still describe about real death like?

These questions cannot be resolved overnight. However, let us explore some other surprising discoveries about death - the law of immutability of nature.

1. Decomposing corpses actually smell quite . sweet

As everyone knows, human flesh and animals during the decomposition process will emit a foul smell, very hard to smell.

In fact, this decomposition smell is a very complex compound, mixed from over 400 different volatile chemicals.

The smell of decomposition is a very complex compound.

According to the latest research, among the compounds in rotten odor emitted from corpses also includes 5 types of esters - a type of organic compound with a pleasant sweet aroma. These 5 types of esters include 3-methylbutyl pentanoate, 3-methylbutyl 3-methylbutyrate, 3-methylbutyl 2-methylbutyrate, butyl pentanoate and propyl hexanoate.

The corpse is fragrant, and this smell is only in the body.

In particular, these 5 types of esters can only be found in human corpses and not in the bodies of other animals. In addition, these types of esters can also be produced from plants and fruits when rotting.

It is interesting to note that for people who have a lot of exposure to the corpse, such as forensic examiners or funeral service providers, the corpse will have a "sweet" smell and not stink like normal people. feel.

2. Hair, toenail nails elongated after death is . fictitious

There is a lot of information to suggest that human hair, toenails and nails will continue to grow long after the body has died. This is extremely . fictitious because after death, metabolism will stop working immediately and therefore no body parts will continue to grow.

However, the truth is that when looking at corpses after a while, we can see their hair and toenails and nails . really long.

Hair hair still grows after death?

Why so? Scientists reasoned that the body was dehydrated, causing other parts to shrink, and hair and toenails and nails looked longer than before.

3. People will die if telomeres - the cause of aging disappears

In the early days of cellular doctrine, many people thought that human cells were immortal, and could copy themselves until humanity ended life.

But in 1961, the idea was completely dismissed when scientists proved that cell division is limited. A cell will "fall" after dividing about 50-70 times.

Telomeres (red part).

By the early 1970s, scientists discovered telomeres - sequences that repeat DNA at the ends of chromosomes. Telomeres play a role in protecting chromosomes during cell division, keeping chromosomes from sticking together.

But it was not until 2012 that scientists showed evidence that telomeres were involved in the aging process. Specifically, telomeres will be shortened after each cell divides itself. When telomeres are so short that the division will end and then one cell will "die".

Measuring the length of telomeres in the cell will help predict the life expectancy of people.

If a person possesses telomeres in each cell of a long length, the cell division will take longer, helping the person live longer. Therefore, measuring the length of telomeres in the cell will help predict the life expectancy of people.

4. The younger we are, the more afraid we are to die

A study in the United States found that people in their 40s and 50s were more worried about death than those aged 60-70 years. Another study showed similar results for people in middle age and adolescents (18-25 years).

People in their 40s and 50s are more worried about death than those aged 60-70 years.

Besides, another study also found that in men the average worry about death will peak at age 20 and will gradually decline over time.

This worry for men at age 60 will no longer be a concern. For women, about 40-50 years old is a time when women will be less worried about this.

We are not afraid to die.

This is really a surprising result when people in their most youthful years worry about "goodbye to the world" than those in the "near far away" land.

But in terms of psychology, young people have a future ahead so they tend to be "afraid of death" than older people.
