Today, we would like to talk about the differences between men and women. You might say that you’ve known about these differences for your entire life, but it’s not that simple. We are sure that we’ll be able to highlight a few facts you’ve never heard of before. And in the bonus section, you’ll find out where the fashion for high heels came from.
The length of fingers
Let’s conduct a short experiment. Place your hand on a flat surface and compare the length of your index and ring fingers. In general, in women, the index finger is longer. In men, the ring finger is longer. How can this be explained?
According to scientists, the length of these fingers depends on the level of male and female hormones that affect the fetus in the womb. So, the reason why the ring finger is longer than the index finger in men is testosterone.
The skin on the heels
Scientists have found out that women’s skin is more hydrated in the décolleté area and on the hands. Only the skin on their heels is dryer than that of men. So, in equal conditions, men’s heels will be smoother.
Breast
You might think, “Why would a man need nipples?” It might sound strange but every person was initially female. When an embryo begins to develop in the womb, the male Y chromosome doesn’t immediately start working.
During the first 5-6 weeks, development occurs only under the influence of the X chromosome, so the nipples have enough time to form. If the embryo is male, the Y chromosome “turns on” after this period of time, and a boy is formed.
Men can even produce milk. Lactation is activated under special conditions, for example, it may appear during treatment with the hormone prolactin.
Vision
Women are better at seeing colors, but men are good at tracking fast-moving objects. This is probably linked to our hunter-gatherer past when men were hunters and women were gatherers.
For example, an orange may appear redder to a man than to a woman. The grass is almost always greener for women because green objects appear more yellow to men.
Gaining muscle mass
Many women have to go to the gym regularly to have a toned body, while a man can just lift a barbell a couple of times to get a 6 pack. So, what is the “ingredient” responsible for muscle development? If you guessed testosterone, you’re right.
In women, it is also produced, but in much smaller quantities. So, it is easier and faster for men to gain muscle mass.
Hair loss
Going bald after the age of 50 is typical for around half of men (and for a quarter of women too). The reason for this is a widespread hereditary disease, androgenetic alopecia, which is also called “male pattern baldness.” Due to this condition, hair follicles shrink, and hair becomes thinner and shorter, and eventually disappears.
Follicle shrinkage can be caused by sensitivity to dihydrotestosterone, a by-product of testosterone. This means that the more muscle-building hormone a man has, the more likely it is that he will become bald.
Adam’s apple
Both men and women have an Adam’s apple, but it’s more prominent in men. Why? The Adam’s apple is the cartilage that protects our vocal cords. It is formed during puberty. Since adult men have larger vocal cords, their Adam’s apple is also more prominent.
By the way, the larger the Adam’s apple, the deeper the voice. There is a theory that our ancestors needed a low voice in order to scare away predators.
Brain size
A man’s brain is larger than that of a woman, but this doesn’t mean that men are intellectually superior to women. Also, some parts of the brain in both sexes are different in size and work differently. For example, the hippocampus, which is involved in learning and creating memories, is larger in women. And the amygdala, which is associated with experiencing emotions and remembering them, is larger in men.
Scientists conducted an experiment: they showed the subjects a video so that they could recall some personal experiences. It turned out that in men, activity was observed only in the right amygdala, and in women, only in the left one.
Beard
At first glance, it might seem that a beard doesn’t provide any benefits. So, why does it grow? There is a theory that the jawline looks more massive thanks to a beard, so its wearer looks stronger and more masculine. Perhaps, our female ancestors tended to choose men with a thick beard as their partners because they thought they would produce healthy offspring with them.
Bonus: Heels
Nowadays, high heels are one of the symbols of femininity, aren’t they? However, in the 17th century, Persian riders used to wear one-inch heels. And since owning horses was a symbol of wealth, heeled shoes also came to signify money and power. The Persians then brought their fashion to Europe.
The French king Louis XIV became a big fan of heels. He even issued a decree according to which only nobles were allowed to wear heels. The higher and redder the heel was, the more powerful the wearer was.
The Sun King only allowed those who he favored the most to wear red heels. But since the 18th century, heels have become a purely feminine attribute, although this didn’t stop rock stars like David Bowie and The Beatles from wearing them.

These bugs come out at nighttime, and attacking victims, they silently kill or leave them with a lifelong infection
When Emiliana Rodriguez was a little girl, she recalls watching friends play a nighttime soccer match when one of the players abruptly died on the pitch.
Unaware of what had transpired, Rodriguez, a native of Bolivia, developed a phobia of the dark and the “monster”—the silent killer known as Chagas—that she had been told only appears at night.
Chagas disease is a unique sort of illness that is spread by nocturnal insects. It is also known as the “silent and silenced disease” that infects up to 8 million people annually, killing 12,000 people on average.
Emiliana Rodriguez, 42, discovered she had to live with Chagas, a “monster,” after relocating to Barcelona from Bolivia 27 years ago.
“Night is when the fear generally struck. I didn’t always sleep well,” she admitted. “I was worried that I wouldn’t wake up from my sleep.”
Rodriguez had specific tests when she was eight years old and expecting her first child, and the results indicated that she carried the Chagas gene. She recalled the passing of her buddy and remarked, “I was paralyzed with shock and remembered all those stories my relatives told me about people suddenly dying.” “I wondered, ‘What will happen to my baby?’”
Rodriguez was prescribed medicine, though, to prevent the parasite from vertically transmitting to her unborn child. After her daughter was born, she tested negative. Elvira Idalia Hernández Cuevas, 18, was unaware of the Mexican silent killer until her 18-year-old son was diagnosed with Chagas.
Idalia, an eighteen-year-old blood donor from her birthplace near Veracruz, Mexico, had a positive diagnosis for Chagas, a disease caused by triatomine bugs, often known as vampire or kissing bugs and bloodsucking parasites, when her sample was tested.
In an interview with the Guardian, Hernandez stated, “I started to research Chagas on the internet because I had never heard of it.” When I read that it was a silent murderer, I became really afraid. I had no idea where to go or what to do.
She is not alone in this; a lot of people are ignorant of the diseases that these unpleasant bugs can spread. The term Chagas originates from Carlos Ribeiro Justiniano Chagas, a Brazilian physician and researcher who made the discovery of the human case in 1909.
Over the past few decades, reports of the incidence of Chagas disease have been made in Europe, Japan, Australia, Latin America, and North America.
Kissing bugs are mostly found in rural or suburban low-income housing walls, where they are most active at night when humans are asleep. The insect bites an animal or person, then excretes on the skin of the victim. The victim may inadvertently scratch the area and sever the skin, or they may spread the excrement into their mouth or eyes. This is how the T. cruzi infection is disseminated.
The World Health Organization (WHO) estimates that between 6 and 7 million people worldwide—roughly 8 million people in Mexico, Central America, and South America—have Chagas disease; the majority of these individuals remain oblivious to their illness. These estimates are provided by the Centers for Disease Control and Prevention (CDC). The persistent infection might be fatal if untreated. According to the Guardian, Chagas disease kills over 12,000 people year, “more people in Latin America than any other parasite disease, including malaria.”
Despite the fact that these bugs have been found in the United States—nearly 300,000 people are infected—they are not thought to be endemic.
While some people never experience any symptoms, the CDC notes that 20 to 30 percent experience gastrointestinal or heart problems that can cause excruciating pain decades later.
Furthermore, only 10% of cases are detected globally, which makes prevention and treatment exceedingly challenging.
Hernández and her daughter Idalia went to see a number of doctors in search of assistance, but all were also uninformed about Chagas disease and its management. “I was taken aback, terrified, and depressed because I believed my kid was going to pass away. Above all, Hernandez stated, “I was more anxious because I was unable to locate any trustworthy information.”
Idalia finally got the care she required after receiving assistance from a family member who was employed in the medical field.
“The Mexican government claims that the Chagas disease is under control and that not many people are affected, but that is untrue,” Hernández asserts. Medical practitioners misdiagnose Chagas disease for other heart conditions because they lack knowledge in this area. Most people are unaware that there is Chagas in Mexico.
The World Health Organization (WHO) has classified chagas as a neglected tropical disease, which means that the global health policy agenda does not include it.
Chagas is overlooked in part because, according to Colin Forsyth, a research manager at the Drugs for Neglected Diseases Initiative (DNDi), “it’s a silent disease that stays hidden for so long in your body… because of the asymptomatic nature of the initial part of the infection.”
Forsyth went on to say, “The people affected just don’t have the power to influence healthcare policy,” making reference to the impoverished communities. It’s kept hidden by a convergence of social and biological factors.
Chagas, however, is becoming more well recognized as it spreads to other continents and can also be transferred from mother to child during pregnancy or childbirth, as well as through organ and blood transfusions.
The main objective of the Chagas Hub, a UK-based facility founded by Professor David Moore, a doctor at the Hospital for Tropical Diseases in London, is to get “more people tested and treated, and to manage the risk of transmission, which in the UK is from mother to child,” according to Professor Moore.
Regarding the WHO’s 2030 aim for the eradication of the disease, Moore stated that progress toward it is “glacial” and added, “I can’t imagine that we’ll be remotely close by 2030.” That seems improbable.
Two medications that have been available for more than 50 years to treat chagas are benznidazole and nifurtimox, which according to Moore are “toxic, unpleasant, not particularly effective.”
Although the medications are effective in curing babies, there is no guarantee that they will prevent or halt the advancement of the condition in adults.
Regarding severe adverse effects, Rodriguez remembers getting dizziness and nausea as well as breaking out in hives. She completed her therapy, and she gets checked out annually.
Moore goes on to say that while creating stronger anti-Chaga drugs is crucial to stopping the disease’s spread, pharmaceutical companies are currently not financially motivated to do so.
As president of the International Federation of Associations of People Affected by Chagas condition (FINDECHAGAS), Hernández is on a mission to raise awareness of the condition until there is a greater need on the market for innovative treatments.
In Spain, Rodriguez is battling the “monster” as part of a campaign to increase public awareness of Chagas disease being conducted by the Barcelona Institute for Global Health.
“I’m tired of hearing nothing at all,” Rodriguez declares. “I want Chagas to be discussed and made public. I’m in favor of testing and therapy for individuals.
They are being heard, too.
World Chagas Disease Day was instituted by the WHO on April 14, 1909, the day Carlos discovered the disease’s first human case.The WHO states that “a diversified set of 20 diseases and disease categories are set out to be prevented, controlled, eliminated, and eradicated through global targets for 2030 and milestones.” And among them is Chagas.
To prevent a possible infestation, the CDC suggests taking the following steps:
Close up any gaps and fissures around doors, windows, walls, and roofs.
Clear out the rock, wood, and brush piles close to your home.
Put screens on windows and doors, and fix any tears or holes in them.
Close up gaps and crevices that lead to the exterior, crawl areas beneath the home, and the attic.
Keep pets inside, especially during the evening.
Maintain the cleanliness of your home and any outdoor pet resting places, and check for bugs on a regular basis.
If you believe you have discovered a kissing insect, the CDC recommends avoiding crushing it. Alternatively, carefully put the bug in a jar, fill it with rubbing alcohol, and then freeze it. It is then recommended that you bring the bug’s container to an academic lab or your local health authority so that it can be identified.
