Medical Video: Why Do Women Live Longer Than Men? | Earth Lab
After being labeled as a weak gender for a long time, it's now your turn to be proud of being a woman, because you have a number of advantages that men don't have.
1. Long life
Of the 49 oldest people recorded in the world today, only two of them are men. A woman born today has a life expectancy reaching 79.8 years, aka five years longer than men. Although this age gap has narrowed a little in recent years, the life expectancy of men has now been achieved 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 a chromosome bundle that forms DNA in each cell. Chromosomes consist of 2 pairs: women have two X chromosomes, while men have X and Y chromosomes. These simple differences indirectly change the way cells develop. Having two X chromosomes, women keep multiple copies of each gene, which means they have a backup if one is damaged. Men have no reserves, plus a number of external factors that are more common in men - for example in terms of accidents and diseases related to lifestyle 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 tracks the number of new white blood cells, known as T-cells, in 46 healthy men and women aged 20 - 62 years. In both sexes, the thymus gland produces T-cells, making fewer cells with age. But women still have new T-cell levels than men of the same age, according to a report in New Scientist magazine. The researchers then looked at statistics for deaths in the UK due to pneumonia and influenza between 1993 and 1998. They found more men than women died of diseases and lifestyles that reflected differences in thymus activity between the sexes.
2. A better sex life
The world record noted that Danish women reached 222 orgasms on one masturbation time!
Women's bodies allow them to be able to have orgasms repeatedly even when they do not voluntarily reach multiple orgasms or are not ready to face multiple orgasms, both during penetrative sex and masturbation. Interestingly, multiple orgasms do not have to occur immediately in a row. With consistent and continuous stimulation and passion, a woman has the power to continue to enjoy unlimited orgasms. Conversely, men do not have the ability to double orgasm because a man's body needs a recovery period from one orgasm.
In addition, a new survey shows that on average women enjoy the best sex in their lives at the age of 28 while men lag behind five years. According to the poll, a man must wait until they turn 33 before they reach the peak of their sexual desire. These findings break previous studies which state that male sexual peaks are at age 18 and women at 30.
Women can better understand themselves and find what works and not in sex, faster than men. "Like most things, sex will be better the more you do it and the more you will be good at it," said sex and romance expert Tracey Cox. So it makes sense for men to have better sex at age 33 than 18, because they need more time to control themselves and control orgasm, and to understand a woman's sexual system that is more complex.
3. More resistant to head and neck cancer
National Cancer Research statistics show that since 2015 around 30,000 men will be diagnosed with oral or pharyngeal cancer, while women only have around 12,000. For cases of esophageal cancer, at least 14,000 men can be diagnosed with this disease, compared to the total accumulation of women who only reached 3,000 cases.
Both cancers are strongly associated with tobacco use and excessive alcohol consumption. "Although there are more and more women who smoke and drink alcohol, the number of smokers and major alcohol drinkers is still held by 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. Opportunities are lower for melanoma
The study headed by A. Joosse (2011) in the Munich Cancer Registry found that gender differences contributed to the 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 spread to lymph nodes and visceral metastasis (42 percent and 44 percent lower). In addition, women have an estimated survival advantage of up to 20% even after being diagnosed with cancer, including in-transit and lymph node cancers, but do not include non-visceral metastases.
Skin melanoma in women turns out to have a lower tendency to metastasize (spread), and researchers suspect that this is due to differences in mother tumor interactions in female and male bodies.
This risk gap can be caused by the frequency and intensity of outdoor activities that are more dominated by men, such as work and exercise. Although it is not common for melanoma cancers to attack at a young age, the symptoms of melanoma can start when they reach their 50s and 60s, due to accumulated skin damage over time without sunscreen protection.
5. A keener sense of smell
Men and women are very different in evaluating their perception of odor. Women can identify more types of smell 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, Brazilian Ministry of Research and Technology.
The sense of smell of women is indeed sharper than men, because women have 50 percent more cells in olfactory bulb in their brain (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, sex differences in the sense of smell may be based on different social behavioral factors and can be linked to each individual's perception of smell, which is naturally related to experience and emotion. This also underlies the presumption of researchers who believe that the superiority of a woman's sense of smell is cognitive or emotional ability, not just perception.
6. Can detect more than 100 million colors
Humans are generally trichromatic creatures, have three types of color receptors (cone cells) in their eyes. Each color receptor can accept about 100 different colors, which means that a normal human being can identify around 100 ^ 3 colors, aka one million colors at a time.
Another case with tetrachromatic as in a number of fish, birds and insects, which allows them to have four types of color receptors. Some humans are reported to include tetrachromatic, allowing them to identify various colors up to 100 million different colors. Of course, because none of us really knows how the world is seen by others, these people with visual conditions like "super humans" will not realize this ability.
"Tetracromatic is proven to be owned by a handful of women," Dr. Jay Neits, researcher in color and ophthalmology at University of Washington in Seattle, "although the frequency and what is done by a number of tetrachromatic women is still unclear."
Tetracromatic is likely to occur in women with color blind boys or fathers. The red and green color receptor genes found on the X chromosome, which are doubled by women. Tetrachromatic women are believed to carry three types of genes with ordinary cone cells and one type of mutant. Neitz estimates that only about 2 percent of women have genetic mutations that cause extra cone retina, and there is still no reliable test that can really predict whether a person really has "super vision" or not.
Conchetta Antico, a local painter from San Diego, California, United States, is one of the tetrachromat women.
