Is it true that women live longer than men? & bull; hello healthy

After being labeled as a weak gender for a long time, now is your turn to be proud of being a woman, because you have a number of advantages that are not shared by men.

1. Long life

Of the 49 oldest people on record in the world today, only two are male. A woman born today has a life expectancy of 79.8 years, or five years longer than a man. Although this age gap has narrowed slightly in recent years, the current life expectancy of men has been attainable by women since 30 years ago.

Researchers believe that there are many factors that can cause women to have a greater survival rate than men. One of them is the DNA-forming chromosome bundle in each cell. Chromosomes consist of 2 pairs: women have two X chromosomes, while men have an X and a Y chromosome. This simple difference indirectly changes the way cells develop. Having two X chromosomes, women keep multiple copies of each gene, meaning they have a spare in case one of them breaks. Men have no reserves, plus a number of external factors that are more common in men - for example in terms of accidents and lifestyle-related illnesses such as heart disease and cancer.

Researchers at Imperial College School of Medicine in London found that women produce white blood cells that are more resistant to infection than men of the same age. A team led by Dr. Richard Aspinall and Dr. Jeffery Pido-Lopez tracked the number of new white blood cells, known as T-cells, in 46 healthy men and women aged 20 to 62 years. In both sexes, the thymus gland produces T-cells, making fewer cells with age. But women still have new levels of T-cells than men the same age, according to a report in New Scientist magazine. The researchers then looked at statistics for deaths in the UK from pneumonia and influenza between 1993 and 1998. They found more men than women died from the disease and lifestyle reflecting differences in thymus activity between the sexes.

2. A better sex life

The world record records that a woman from Denmark reaches 222 orgasms in one masturbation!

Women's bodies allow them to have multiple orgasms even when they do not voluntarily achieve multiple orgasms or are not ready for multiple orgasms, either during penetrative sex or masturbation. Interestingly, multiple orgasms don't have to happen immediately in succession. With consistent and continuous stimulation and arousal, a woman has the power to continue enjoying orgasms without limits. Conversely, men do not have the ability to have multiple orgasms because the male body needs a recovery period from one orgasm.

Additionally, a new survey shows that on average women enjoy the best sex of their lives at age 28 while men are five years behind. According to the poll, a man has to wait until they are 33 before they reach the peak of their sexual desire. This finding refutes previous research which stated that men's sexual peaks were at 18 and women at 30.

Women are better able to understand themselves and find out what works and what doesn't with sex, faster than men. "As with most things, sex gets better the more you do it and the more good you are at it," says sex and romance expert Tracey Cox. So it makes sense for men to have better sex at age 33 than at 18, because they need more time to master and control orgasms, as well as to understand a woman's more complex sexual system.

3. More immune to head and neck cancer

Statistics from National Cancer Research show that since 2015 about 30,000 men in total will be diagnosed with oral or pharyngeal cancer, while only about 12,000 women. For cases of esophageal cancer, at least 14,000 men can be diagnosed with the disease, compared to the total accumulation of women of only 3,000 cases.

Both of these cancers are closely related to tobacco use and excessive alcohol consumption. "Although the number of women who smoke and drink alcohol is now increasing, the number of smokers and alcohol drinkers is still mainly men, so the development of the risk is still much higher for men," said J. Leonard Lichtenfeld, MD., Deputy head of the medical team. American Cancer Society.

4. Lower chance of melanoma

Research led by A. Joosse (2011) at the Cancer Registry Munich found that gender differences have a role in risk factors for the emergence of melanoma, aka the rare but most malignant type of skin cancer. Of the 11,000 cases of melanoma, women had a 38 percent survival rate compared to men, and were significantly less likely to develop lymph nodes and visceral metastases (42 percent and 44 percent lower). In addition, women have an estimated survival advantage of up to 20% even after a diagnosis of cancer, including in-transit and lymph node cancers, but excluding non-visceral metastases.

Skin melanoma in women was found to have a lower tendency to metastasize (spread), and researchers suspect that this is due to differences in the interactions of the tumor parent in the female and male bodies.

This risk gap could be caused by the frequency and intensity of outdoor activities that are more dominated by men, such as work and sports. Although it is not common for melanoma cancer to strike at a young age, symptoms of melanoma can start to appear when they reach their 50s and 60s, due to accumulated skin damage over time without sunscreen protection.

5. A sharper sense of smell

Men and women differ greatly in their evaluation of their perceptions of smells. Women can identify more types of odors than men, according to a study conducted by Prof. Roberto Lent from the Institute of Biomedical Sciences at the Federal University of Rio de Janeiro and the National Institute of Translational Neuroscience, Ministry of Research and Technology of Brazil.

Women's sense of smell is sharper than men, because women have 50 percent more cells in olfactory bulb in their brains (the part of the brain that plays a role in identifying odors), according to a recent study published in the journal PLOS ONE.

In addition, gender differences in sense of smell acuity may be based on different social behavioral factors and can be related to each individual's perception of smell, which is naturally associated with experiences and emotions. This also underlies the presumption of researchers who believe that the superiority of a woman's sense of smell is a cognitive or emotional ability, not just perception.

6. Can detect more than 100 million colors

Humans are generally trichromatic, having three types of color receptors (cones) in their eyes. Each color receptor is capable of receiving about 100 different colors, which means that a normal human can identify about 100 ^ 3 colors, aka one million colors at a time.

Another case with tetrachromatics, such as in a number of fish, birds, and insects, which allows them to have four types of color receptors. Some humans are reported to be tetrachromatic, allowing them to identify a variety of colors with up to 100 million different colors. Of course, since none of us really know how the world looks to others, people in this “superhuman” visual state will not be aware of this ability.

"Tetrachromatic is proven to be owned by a handful of women," said Dr. Jay Neits, researcher in color visuals and ophthalmology at the University of Washington in Seattle, "although the frequency and what some of these tetrachromatic women do is less clear."

Tetrachromatics is likely to appear in women with sons or fathers who are colorblind. The color receptor gene that processes red and green is found on the X chromosome, which women have twice as much. Tetrachromatic women are believed to carry three types of genes with regular cones and one type of mutant. Neitz estimates that only about 2 percent of women have the genetic mutation that causes extra cone retina, and there are still no reliable tests that can really predict whether a person actually has "super vision" or not.

Conchetta Antico, a local painter from San Diego, California, United States, is one of the tetrachromate women.
