The male body contains countless surprises and interesting things. And some of them make many people feel surprised about their existence.

1. "Adam's apple pieces" in the neck

In fact, both men and women have "Adam's apple pieces" in their necks - this thyroid cartilage is intended to protect the vocal cords.

As adults, the cartilage becomes more prominent because they have a larger larynx box.

But when men grow up, the cartilage becomes more prominent because they have a larger larynx box. That is also the reason why the boys have a voice like a male duck.

For women, the larynx also develops but the female hormones in the female body do not allow them to thrive. As a result, females when they reach puberty often have higher voices than men because the vocal cords are not too loud, preventing the voice from coming out.

2. Men are older than women

There is a fact that even though they are the same age, women always look "older" than men. Why?

The aging of men in the skin will not be much and slower than the weaker sex.

Under the action of hormone testosterone, male skin is thicker than female. At the same time, the "evaporation" of collagen - the substance that binds cells in the skin more than women - also occurs less. Therefore, the skin aging in men will not be much and slower than the weaker sex.

However, because men are often extremely lazy to take care of their skin, they are prone to external conditions such as sun and dust . which adversely affect the skin.

Men's skin is thicker than female.

Along with that, over time, men's skin also becomes thinner, while in women, due to better care, the thickness will continue to maintain until menopause.

3. Men also have developed "milk glands"

Men also have routes that can produce milk, but this is a sign of an abnormality.

Not wrong, you're reading it right. Men also have routes that can produce milk. But this is a sign of an abnormality in the male body.

5. Men also originate from women

In the first 5 to 6 weeks, the Y chromosome does not work, only the X chromosome.

Believe it or not, all the people in the world start to exist like girls. X and Y are chromosomes responsible for determining the sex of an individual.

If two X chromosomes join together during conception, a girl appears. If the X chromosome combined with Y will "mold" a guy.

However, in the first 5 to 6 weeks, the Y chromosome does not work. Only when it works will the embryo begin to develop to divide sex.

6. Men but color sensitivity is very poor

Cones in the retina of men are nearly ½ less than the weaker one.

Men can identify fewer colors than women. The reason is that cones in men 's retina are nearly ½ less than the weaker sex.

So there is nothing too difficult to understand when men's sensitivity is not equal to that of women.
